Nostalgia be damned, this game is objectively bad. Clunky controls, absolutely tiny view size, choppy graphics, this is one of those games that was acceptable as a kid simply because you had nothing else. Thank goodness games have evolved.

Before the internet as we know it. Before broadband and fibre, cable and wifi - there was dial-up. And before that internet of netscape and frames, there were BBSes. This game harks from that era. If you were a dorky kid sitting in front of a 15" CRT monitor with your Compaq 386 whirring away quietly, you probably played this game. It doesn't have the long-term appeal of Keen 4, or the revolutionary impact of Blake …

This was one of the first platformers I ever played when I was 5 years old. The shareware episode was the closest thing to mario I could play on my old black and white DOS laptop. Revising it today, it's remarkably playable, has a charming aesthetic, and the second chapter ramps up the difficulty just enough to keep things interesting. The fact that people don't talk about Cosmo in the same sentence as Commander …

positive · reviewer's own thumbsView post →One of the better platformers of the early 1990's. The later episodes get pretty difficult. Spent dozens of hours of playing Cosmo's Cosmic Adventures when it first came out. 10/10 - this finally came to Steam.
positive · reviewer's own thumbsView post →Pretty fun game considering its age. I finally came back to finish it, 20 years after playing the demo!

positive · reviewer's own thumbsView post →This was probably the first platformer I ever played on a PC. The reason why this is relevant is because I am a very important person on the internet and when I become prime minister of everything I will make it mandatory to play this game at least once. (p.s. it's a pretty good game)
positive · reviewer's own thumbsView post →I have only played the first episode in the shareware version and I'm glad to have the chance to finish it finally after all those years. It's another good platformer from Apogee, got good controls and nice graphics for the time it was release in.....although the spike in difficulty from chapter 1 to 2 and 3 is big but after a lot of attempts you will get it.

positive · reviewer's own thumbsView post →I highly recommend to play and enjoy this old school classic DOS game to play & relive your old childhood memories.
positive · reviewer's own thumbsView post →Still the best game ever. INSANE! GNARLY! OUTRAGEOUS!
positive · reviewer's own thumbsView post →So, I played this game when I was a kid. My brothers, my friends and I LOVED it. Problem was, we only had the first episode. This was back in the days of 'shareware,' when you were ENCOURAGED to share a game, but then you either had to buy the remaining episodes, or unlock the game somehow, or just however it worked. So, we all played Episode 1 over and over, trying to see who could get the highest score, and never really continued our adventure. Fast forward to modern times, when I remembered…

negative · reviewer's own thumbsView post →I played the very first part of this game when I was just a young kid on my dad's Windows DoS machine. I grew to love it and it ultimately fueled my love of video games which has become a central part of my life. Finding this game and rekindling that love while simultaneously experiencing parts 2 and 3 for the first time is something I will always remember. Thank you Steam <3
positive · reviewer's own thumbsView post →At some point I think I bought the entire Apogee / 3D Realms collection and this is one of the games in there. It’s a fairly standard platformer for the era and DosBox diligently emulates the tremendous amounts of strain these games used to put in CPUs back in the day. Meaning that the game plays at below 20 FPS at all times, making it rather unplayable by modern standards. Enemies can hit you as soon as you can see them and often times it’s not really all that clear what actually hit you. As…
negative · reviewer's own thumbsView post →Classic game from my childhood. Only complaint is that the toll-free number in the manual no longer works, so I'm not sure where I can order an additional floppy disk or get my book of cheat codes.
positive · reviewer's own thumbsView post →The Dark Souls of Platformers.
positive · reviewer's own thumbsView post →Another game that did not stand up to the test of time. Buy for nostalgia, but if you've never heard of it, skip it.
negative · reviewer's own thumbsView post →Damn, Bobby Prince did the soundtrack for a chunk of my childhood. Outside of the big hits, I didn't realize he also did Cosmo's Cosmic Adventure, Bio Menace, Math Rescue Plus, Blake Stone, and Pickle Wars. www.mobygames.com/person/728/r...

positive · AI labelView post →Yassss! One of my first PC based platformers. Great game, alongside Bio Menace, Monster Bash, And Cosmo's Cosmic Adventure, just to name a few. I really thought you through these games onto a modded Game Gear :D
positive · AI labelView post →“I wonder if this game is as hard as I remember. Maybe I just tried to play it when I was too young.” Lol, lmao even, this game is so hard. 10/10

positive · reviewer's own thumbsView post →Nostalgia overload!
positive · reviewer's own thumbsView post →You play a little alien which got lost on a foreign planet. Now you have to search for you parents. You don't have weapons, but you can jump on (most) enemies to defeat them. And you can climb walls. In every level there is an exit which you have to reach. There are plenty of secret areas in the game. The game is divided in three parts. Each part has 10 Levels. The steam version includes all three parts of the game. One of the best "old" games in my opinion
positive · reviewer's own thumbsView post →Best game from my childhood. Didn't realy know how to play then but I loved it and today it's still a lot of fun!

A game sooo old and soo classic that I never played before? Well.. Not any more.. I play though all 3 episode and it took me alot longer then expect. A very classic 2d side-scrolling platform jumper. Old school easy to die with only 3 health to begin with(ya.. u can get 2 more but they are hard to find and get). Quite classic story plot with the first 2 episode ends with cliff…

neutral · AI labelView post →Played this game back in the day when I was a kid, super easy to play just make sure you press the jump button which is the CTRL button. Look out for the stupid little birds
positive · reviewer's own thumbsView post →Maybe it was a great game for its time, but for now VGA graphics made me very uncomfortable. FPS rate also very low. not good for your eyes, but if you wanna see how '90s game were look like, give it a try.
negative · reviewer's own thumbsView post →Well, I can confirm its a 100% authentic 1992 original version of the FULL paid for game. Works fine on my Windows 10 Creators Update machine. Classic platformer, good mechanics, catchy 8 bit tune and a good deal of challenge later on. Ignore the playtime - I'm old enough to have played this through already! https://en.wikipedia.org/wiki/Cosmo's_Cosmic_Adventure

Aethra Chronicles, Robo, Heartlight, Electroman, Zeliard, Solar Winds, Shadow of Yserbius, Cosmo's Cosmic Adventure, Hocus Pocus, Radix: Beyond the Void, Fury3 and Terminal Velocity ... #games #gamesky #rpg #retrogames
neutral · AI labelView post →If you don't count Solitaire then I think it'd probably be Cosmo's Cosmic Adventure. I suppose technically it might have been this other game where you're a rabbit and it somehow involved spelling, but I don't remember what that was called and it was only on my friend's family's computer and it was educational so it doesn't count. It was on a floppy disk that was actually the floppy kind.
neutral · AI labelView post →one of the greatest game ever :D
positive · reviewer's own thumbsView post →Only buy this game if you're nostalgic for it. The hard and painfull truth is that DOS platfomers are pretty bad, even the great ones at the time. It runs at 15fps, where the snes at the time ran at 60. This game is from a time where being able to play a game on a pc with scrolling was novel.
negative · reviewer's own thumbsView post →Excellent game, especially since it includes all three episodes.
positive · reviewer's own thumbsView post →A classic of my childhood :)
positive · reviewer's own thumbsView post →Fairly unique platformer. You are a naked green alien with red hair and suction cups for hands. Besides the basic jumping on enemies attack, you get bombs as both a weapon and a utility to get through the level. The suction cup hands allow the player to scale up walls which is absolutely necessary for some levels. I grew up with the first game, but finally get to play the other two.
positive · reviewer's own thumbsView post →Good old-school sidescrolling fun. Might have to sit back from the screen for this one, the old graphics are a little garish at times, especially the backgrounds on some of the mid to later levels. The first episode was a great warm-up for the last two episodes which are pretty challenging; I beat the last level of episode two on accident. Best video game ending, 10/10.
positive · reviewer's own thumbsView post →Tags: Platformer Additional Tags: Delete Local Content & Remove from Library TLDR: DOS-era. Does not have the appeal of some more iconic games from the era. DOS not a friendly platform to make good platformers to begin with. Abandonware Grade. Scrolling of screen is done in bursts and does not feel fluid in dosbox. Controls are slow and sluggish. Sprites have a cartoony charm to them. Retro audio can grow on you. Music track loops way too much and is way too energetic and full of percussions…

positive · reviewer's own thumbsView post →One of the more disappointing Apogee games. The intro steals the ZZ-Top in its own DOS render, but the rest of the music is irrating and repetitive. The gameplay is so jittery. The movent and scrolling feels like 2 frames per second it's hard to see what the f*ck is going on. CTRL to jump and ALT to take a sh*t, basically you run through levels collecting points and jumping on enemies heads. Sounds like Mario, but Mario is 100000 time better. Meh. 2/10

neutral · AI labelView post →Still waiting (in vain?) for that Cosmo's Cosmic Adventure remaster. That game was my favourite growing up and I'm bummed that the remaster has stalled or been cancelled.
positive · AI labelView post →Cosmo's Cosmic Adventure is a charming slice of early PC gaming history that still feels distinctive decades after its original release. Developed and published by Apogee Entertainment, the game captures a transitional moment in platformer design, when developers were experimenting with new movement ideas and personality-driven protagonists on MS-DOS hardware. While its premise is simple—a young alien separated from his parents after a spacefaring mishap—the execution is filled with creativity,…
positive · reviewer's own thumbsView post →I played all 3 games, starting at age 11. It is hard. You have to fail and fail and fail until you don't. As a result, it is SO satisfying when I absolutely nail a level. I played this, Commander Keen, Challenge of Ancient Empires!, Doom and Wolfenstein. Cosmo was, by far, my favorite. I listened to Bridge Over Troubled Water about 100,000 times as I worked my way to the theme park with my parents. The last level took months to memorize and perfect. Here's hoping I'm not the only weirdo…
positive · reviewer's own thumbsView post →Mine was *probably* Cosmo's Cosmic Adventure, though I never owned it. The first game that I owned I think was Pokémon Stadium. That or Kirby's Tilt and Tumble.
neutral · AI labelView post →Ha, I haven't thought about Cosmo's Cosmic Adventure in years. Loved that game!
positive · AI labelView post →What’s your “no one but me remembers" game? Cosmo's Cosmic Adventure! I had so much fun with this game. The stormy woods level was my favorite.
positive · AI labelView post →Unlimited continues from level start and save feature is enough to make this enjoyable.
positive · reviewer's own thumbsView post →Played this when I was a kid and forgot the name of it. A buddy helped me figure out what game it was after describing it and I'm pleased to say I remembered it fondly and I'm going to enjoy finally beating it. It might be a bit difficult to master for people who did not play it in the 90's though, so be advised.
positive · reviewer's own thumbsView post →Good old DOS game. The graphics are fine, the fact that only jumping on the head can be used to defeat enemies and no weapons are available is a nice twist. Regarding the difficulty some levels were quite hard, especially because massive waves of enemies were present. My playthrough: https://www.youtube.com/playlist?list=PLGg9onWtxOgoZUevjzTridfmbAWLaG-bx
positive · reviewer's own thumbsView post →One of the first video games I ever played, if not the first. If you enjoy old-school platformers like Super Mario Bros. and Sonic the Hedgehog, you might like this one.
positive · reviewer's own thumbsView post →Such a cute arcade game. I'm a bit biased, as my family had a dog named Cosmo when we first discovered this game many years ago, but I'm glad to have been able to pick it up again all these years later. It's not the easiest game, but it is fun and worth the few dollars it costs.
positive · reviewer's own thumbsView post →I don't know if anyone who did not play this game as a child will enjoy this game and I don't care! I love Apogee and its early games. This brings so many memories!
