Fun short implementation of an interesting concept, easy to complete in terms of 100% achievements. A little bit too heavy on CPU for what it is. There could also be a bigger map variety. Overall I'd give it a slight positive note of like 5.5/10, as long as you get it in some bundle or for cheap.

Difficult Achievement(s): No. Intro You are a scientist that is located in a lab. Nobody knows what you are doing, but somehow, you are shrinking bit by bit. Luckily, it turns out there are antidote formulas and materials for making it hidden in the lab - you just need to find them and make the antidote yourself. Well, that's the gist of what's happening in Size…

negative · reviewer's own thumbsView post →Random Game of the Day 118 - Ratchet and Clank: Size Matters My first and only R&C game. I've played demos of some of the other games and bought this one on clearance, but just could never get into the series. I do enjoy the characters and world though and enjoyed the movie
neutral · AI labelView post →Size Matters is a hybrid first person adventure/puzzle game and 3D platformer. You're in a small lab and you inhale chemicals that make you shrink. To fix the problem you must create other chemicals, but as you're shrinking, you're against the clock and the environment to operate the various fictional apparatus. It's a simple premise that might work well if the implementation was better and the developer was more ethical (more on that below). On the upside, the game does feature…
negative · reviewer's own thumbsView post →As a scientist in real life, I really wanted to like this game, however, it was mostly a boring letdown. The basic mechanics of the game involved mixing various chemicals together to create new chemicals to stop yourself from shrinking and go back to your normal size. The gameplay is intuitive and straightforward, making it easy to pick up and play. The game also requires patience and careful planning to succeed in your goal. This balance of accessibility and difficulty made the game engaging…
negative · reviewer's own thumbsView post →In Size Matters, the premise is that you are a scientist who has accidentally dumped shrinking formula on themselves in a lab accident. In practice, however, this is wholly irrelevant save for the “setting” of the areas. The game is all about the mechanics. You start out large, but as the game goes on, you get progressively smaller and smaller. There are several pieces of lab equipment on benches around the lab, beakers of various chemicals, and notes – both written on the walls and on…

neutral · AI labelView post →I mean, it's cool. But it's not something you can put much time into and so isn't really worth much money. It just kinda feels like a cool tech demo for something that could be much better.

You can now play "Ratchet & Clank: Size Matters" for the PlayStation 2 with achievements over at RetroAchievements! retroachievements.org/game/19108
neutral · AI labelView post →Given that it's a ripoff of a free game and that the gameplay is around 2h, and repeating the same thing over and over, I would say don't buy it. Unless you have it in a bundle or from somewhere free, don't bother with it.
negative · reviewer's own thumbsView post →of all the games to play to dust off my PS4… Why did I pick Ratchet and Clank Size Matters? I get that it’s a PSP game but my god it is an absolute janky mess and at this point I’m 68% percent only continuing just to say I did it… (Also the dream sequence gave me a dang headache)
negative · AI labelView post →“Which macro/micro concept in media you found disappointing?” When the character is shrunk, but then immediately enters an environment where everything was also shrunk to a matching size, making the size change pointless. AKA the movie Downsizing or the game Ratchet and Clank: Size Matters
neutral · AI labelView post →"Yeah Mr. White! Yeah Science!"
positive · reviewer's own thumbsView post →Size Matters is a gigantic disappointment. Never playing it again. Holy shit this game was poorly made/balanced. As a RaC fan, I was looking forward to this set going live, but revisiting it from when I was a kid, HOLY FUCK the rose-tinted glasses were strong until they got slapped clean off.
negative · AI labelView post →In the game Size Matters, you shrink and have to craft keys using found recipes. You need to make three different keys to create an antibody. Once you have all the keys, you can craft the antibody, which returns you to your original size. The game is only worth buying when it’s on sale, as it provides just a short, casual fun experience.
positive · reviewer's own thumbsView post →Not a lot of fun to play more than once
negative · reviewer's own thumbsView post →Made me unimaginably happy to finally hear some one other than me mention Death Jr on the show. But Ratchet and Clank Size Matters is my favorite PSP game by far.
positive · AI labelView post →Nothing in life is objective. Except for the fact that Size Matters has THE worst shotgun in gaming How can you look at the game with the Concussion Gun and go “yep. Definitely better than Into The Nexus, 2016 AND Rift Apart” lmao
negative · AI labelView post →This is a neat gimmick, but it's only fun if you have half a dozen people shouting "no, don't do that, do X!" In that sense, this is a party game or a twitch game. If that's you, ignore me. If you are a friendless hermit (like me) this game feels like it would have been an amazing minigame in something like Half Life 2 or a No One Lives Forever reboot, but on its own it's not enough for a full game. It's still worth $1-$2 (I paid $3.5). https://youtu.be/VQzXiIiMSD4 PS: I enjoyed pretending…

positive · AI labelView post →Size Matters - A colourful spin on another game, Inch By Inch. You're a professor, you accidentally shrunk yourself, now you have a limited amount of time in order to reverse the effects or be lost to the dust void for ever. The game itself is pretty straight forward, with puzzle solving as the center. Highly recommend this game, really fun, but very little in the way of replay-ability.
positive · reviewer's own thumbsView post →Great mechanics, but lacks in content. More challenge and levels would have been nice.

positive · reviewer's own thumbsView post →After 1 level you've seen everything the game has to offer. Absolutely pointless.
negative · reviewer's own thumbsView post →19. Secret Agent Clank (PSP, replay) The stealth mechanics are incredibly underbaked and it exacerbates the issues Size Matters had such as a bad bolt economy and bogging the game down with even more and even longer gimmicky sections. Arguably the worst in the series

neutral · AI labelView post →Love seeing some Size Matters doodles-! I played the original game first as a kid at my cousin's house, but Size Matters was the first game that I truly owned. (A birthday gift from the same cousin alongside a PSP, lol). Some people hate it, but I will always have a soft spot for it.
positive · AI labelView post →Ratchet & Clank: Size Matters (PSP) I wanted to like this, but it's easily the weakest R&C game I've played. While it's neat to have an original portable Ratchet game, it's just too much of a slog. Enemies are bullet sponges and weapons feel piss weak, plus the controls are limited by the PSP 4/10
negative · AI labelView post →Fun little game to 100%. Recommend it if you're fine with spending a couple bucks for a 3-5ish hour experience.

positive · reviewer's own thumbsView post →That sounds like the distant cousin to the "Sprout-o-Matic" from hit game, "Ratchet and Clank : Size Matters" and I love that game with an autistic interest and attachment
positive · AI labelView post →I’m a Zelda fanatic, *But*, I’ve always wanted to be a game artist for Sony. Ever since I first got my own psp, playing through Size Matters, I made it a goal [a ludicrous goal for a 6 y/o] that I would study art to become any part for the art direction team at Sony. Sonic or T&C, I wanted it bad.
positive · AI labelView post →My main complaint is that the game is EXTREMELY short for what it is. Everything feels unfinished and a bit wonky. I appreciate the mechanic of decreasing in size, which is a new twist in a game that doesn't feel like a puzzle... But everything else ends up working against you. You are left sometimes waiting for several minutes while things just happen in the background, with no gameplay while you just wait. The amount of content it offers could also be better but, given how short it is, you…
negative · reviewer's own thumbsView post →Cool concept and pretty chill. Quick to 100% and honestly depending on the person could be "too easy", but it is nice that they add custom difficulty so you can make it semi-challenging. Super cheap key and fun to kill an hour or two on. 6.5/10
positive · reviewer's own thumbsView post →Rating:2/10 Completion difficulty:2/10 Honestly, the game's just extremely short. You play it once or twice, you see everything you need to see. Shrinking goes from not an issue to making the level impossible nearly instantly, making the game's main draw just not that important.
negative · reviewer's own thumbsView post →Absolute garbage
negative · reviewer's own thumbsView post →Pretty fun game, that unlike the modern trend can mostly (aside from +/- 5 achievements that require constrained difficulty settings) be completed in a very chill way. The main issues I have are: - mouse capture issues (I played in windowed mode, and the mouse tends to escape from the game's window, causing me to click on outside stuff while playing and/or to miss whatever I wanted to click on in the game :s) - a few bugs with controls (in particular, very often crouching doesn't work at all)
positive · reviewer's own thumbsView post →#Beat all scenarios plus a custom game Around 4 hours Size matters is a fairly unique game. Here is the pitch: You go into a lab. You are shrinking constantly. You have to make an antidote to stop the shrinking. Lucky for you, everything you need is in the room. Unlucky for you, all those things are everywhere and the recipe for the antidote changes every time you play. You need 3 key (chemicals) to win. Loop: - Find all chemicals (these all have fake names. You can also insert your own) -…
