I really want to like this game. I REALLY do. BUT it's lacking in the most important aspect: the gameplay itself. Don't get me wrong, the characters, OST, and story all seem solid, and the production quality behind those aspects is clearly high, but the gameplay though... that's another story. The hitboxes feel inconsistent, enemy attacks look half-baked, and the dodge timing is frustrating because it's often …

Honestly, this game is perfect if you love combat similar to NieR: Automata/Stellar Blade with the overall mechanics of Risk of Rain 2. Most of the negative reviews are complaints about some of the difficulty which is understandable because on Sinner difficulty it feels very difficult to scale properly while also working against the meter that builds up. You cannot just run around and full clear everything, time is …

I have a lot of thoughts about this game, so I wanted to leave a review to encapsulate my (mostly spoiler-free) thoughts as someone who's probably the target audience for this game.

This could get long, so a quick tl;dr …

This is a game that took me a while to find my voice with, so I want to give some insight to anyone who may be looking to get into this. I won't be talking about the story or the sound design though, I don't believe those things need to be sold to you because they're absolutely stellar and kind of sell themselves, ESPECIALLY the music. This will primarily be about the Gameplay + Early experiences with it. I'll start …

negative · reviewer's own thumbsView post →This game is tough for me to review. I REALLY like the characters, story, visuals, and overall vibe—these are genuinely strong foundations. Everything looks great at first glance, and you can tell the team put heart into the art direction and world-building. But the gameplay isn't clicking for me. Compared to other roguelites like Risk of Rain 2, the progression feels hollow. There's no clear upgrade path, and when you do get a boost, it's usually negligible—a 2% or 5% increase that…
negative · reviewer's own thumbsView post →This game is either Early Access and just not disclosed as that, or its a lost cause. This needs significant changes and updates to be even close to living up to the games that clearly inspire it. Right now it feels like Nier Automata Megabonk and thats a very COOL thing. But the combat is very unfinished, the dodging is extremely inconsistent, it takes far too long to eliminate basic fodder enemies, and its impossible to dodge, parry, or avoid damage when half the screen is covered in smoke,…

neutral · AI labelView post →This game feels like it should be an Early Access game. The game takes some things from games like Risk of Rain 2 or Megabonk but doesn't improve them in any capability. Gameplay feels weird and clunky whent it should feel smoother because combos are a big part of the combat. The lack of information on what to do or search for is frustrating. Game looks horrible, like a Switch game, but not a First Party Switch game, like those horrible ports the Switch has. Game on max settings and I've seen…

neutral · AI labelView post →I'm noticing a lot of people going into this game expecting a Hades 2 when it is in fact a Risk of Rain 2.
positive · reviewer's own thumbsView post →I currently can't recommend this game. The story captivated me from the moment the intro started and they definitely put a lot of effort into the narrative. That being said though, the gameplay needs some major adjustments. Every run for me just ends in pure frustration. Enemies have way too much health and the upgrades feel completely useless. You get back to base hoping in vain that there's some sort of meta-progression, upgrade system, or something that you're missing. All you have is a…
negative · reviewer's own thumbsView post →Art, music, characters and writing are all great. It really feels like a lot of passion was put into it. There is one huge issue though: The core gameplay is kind of undercooked. Basic enemies are damage sponges, which is expected from a roguelike, but the progression is so slow that it feels like punishment. The powerups you're getting from Mementos are very underwhelming. Remember "Hell Maiden"? Every powerup felt like an upgrade and it's very engaging to obtain them. Here, you spend 15…

neutral · AI labelView post →Kernel Hearts is a game that conflicts with me. I don't feel like I'm the target demographic, I'm not its audience. I got it because "well it's something different to what I usually play, might as well broaden my horizons." I started with annoyance at the combat system and ended it feeling disappointed. A broad sense of what its trying to copy is - big open spaces and running around to get stuff, like Risk of Rain. Fast hack n slash action like its DMC, Bayonetta, MGR, Nier Automata.…

positive · reviewer's own thumbsView post →It does not spark joy. 2D art is cool, the story introductions is too. But the 3D assets look and feel half-baked, while the gameplay is feels jank as hell. Aside from the usual hitboxes sometimes not matching up with the visuals, the movement feels uncontrollable. The jump is delayed you have little to no control in the air. I've also found myself questioning the enemy attack hitboxes often while playing. The map is too barren for it's size and the catapult's are a bandaid fix for…

positive · reviewer's own thumbsView post →TLDR, since this is a long review, not worth it in its current state. Either wait for a somewhat steep sale, or wait until a few updates have happened. As much as it pains me, I cannot recommend the game in its current state at the asking price. This game feels like an early access game, in quite a few areas, but it presents itself as a fully finished game. It’s unfortunate, because this game has a lot of interesting ideas and a good amount of potential, but it feels like it doesn’t properly…

Game crashes, bugs out, missing textures. wont load into lvl. I know that it's initial release and bugs will occur, but in this state is almost unplayable Also items, gear, relics and such just not explanatory enough.

negative · reviewer's own thumbsView post →Steam Deck Leaving a quick review for now to say this game is very playable on Steam Deck! (I've played hours of the demo beforehand), but, don't expect to play on max settings. However, my controller inputs weren't configured properly out of the box and so I had to get a custom input mapping; I'm guessing they'll aim for Deck Verification and remedy this soon? (I'm pretty sure the demo had proper inputs without any configuration but don't quote me on that) Anyway, I really love what I've…
positive · reviewer's own thumbsView post →Characters are great, ost is great, story is great, gameplay is not my cup of tea felt like it was attempting to be a roguelike coop devil may cry the combat feels a bit clunky hitboxes on a lot of enemy attacks are either "how the **** did that hit me" or phase through you. A lot of the effects and animations seem very early accessy if that makes sense for example I got a cool move that's a giant cleave with a firesword but it felt like I was swinging a poorly animated neon glowstick I played…

neutral · AI labelView post →This may come down to skill issues, but I just can't recommend this game. This release feels basically identical to what I experienced in the demo months ago - a confusing control scheme if using controller, no way to actually change those controls (the settings for that don't work), combat feeling just kinda basic and despite being centered around perfect dodging attacks, you seemingly can't dodge out of your own attacks. Also the first character's moveset just loves to chain into a launch…
negative · reviewer's own thumbsView post →edit: I ended up refunding. I just don't think this is nearly fun enough. So far, very mid. The dodge in this game is really, uniquely bad. You'd expect something like what Bayonetta has, but half the time you can't even tell if it's working because it's also a dash. Just doesn't feel good. Not sure what the point of lock-on is since in this game you barely have time to use it. When you get hit it just never really feels like you deserve it unless it's a charged attack from a boss or…
negative · reviewer's own thumbsView post →TLDR: The game is too lackluster in polish to recommend. So currently, I do not recommend, with hopes that the game will be patched into something more playable. Long version: Okay, I gotta say, didn't think that it looks like things are just as raw during the full release as they were during the playtests. For the visually impaired, I played the playtest for around 30 hours, hence why I unfortunately have to make comparisons to how things were and where we are at, since the issues that I had…

Lots of bugs and the enemys are just so tanky even at the start game it is clearly for more than one person even more so with the first boss too many adds and the boss being such a tank.

It is held back by fair amount of COOP bugs, lack of detailed stats for mementos, animation locks and 0 customization, be that costumes or hero specific spells Still worth every penny, can't wait for what developers will come up with in the future
positive · reviewer's own thumbsView post →In a game about killing God, it seems God killed it first. This is probably one of the most flawed games I've played in a while. I never really cared about the story, so I'm not gonna talk much about that. My problem is the gameplay. Everything just feels so clunky. The movement, the combat, even just getting around the map. The combat especially feels like a mobile game that got ported to PC without really changing anything. There's not much weight to the attacks and fighting enemies just…

positive · AI labelView post →I was told to expect roguelite Devil May Cry by a friend. What I got was quarter-baked roguelite Nier. Maybe there's still room for that to be fun. But between the awful hitboxes, lacking attack tells, ridiculous difficulty scaling, and a tutorial that tells you how to play Risk of Rain 2 better than it tells you how to play THIS game, quite frankly I think this just isn't fun to play and wasn't ready to release.
negative · reviewer's own thumbsView post →Early Access would've helped this game rather than 1.0 An ambitious game that tries to follow in the steps of Risk of Rain 2's gameplay and it fails miserably. If you played the demo then congratulations, you played the main game as no big changes were added. Enemies will easily get HP bloat and even if you level up your attack by collecting enough pink souls all of them will feel like damage sponges. To add to that, dodging is very clunky and paired with so many enemies to fight with at…
negative · reviewer's own thumbsView post →It's so close to greatness, but I have a good handful of issues with just about every aspect of the combat. The responsiveness is hit-or-miss with the dodging. Sometimes I get a good perfect dodge, sometimes the input just gets eaten and I eat a hit for free. Enemies take forever to kill for the little currency you get after a certain time, but that point gets reached really quickly. You keep fighting to try and get stronger to have a cool build, but the rewards being so expensive means you're…
negative · reviewer's own thumbsView post →This one was pretty rough. The intro when you first launch the game was pretty high quality. A 5 minute long cutscene that's fully voiced explaining the lore and backstory of the game that's pretty well produced. The gameplay itself once the game starts feels like it needs more time in the oven. Something about the controls just feels janky and sluggish. The dodging / dashing specifically feels like it needs to be a lot more responsive considering how hectic some of the fighting can…

Kernel Hearts starts out serviceable, but underneath the surface is an action-RPG that blossoms continously with the more time you put into it. As someone with a love-hate relationship with Risk of Rain 2 and Elden Ring: Nightreign, this particular indie has become one of my favorite roguelites of all time. Success is tied to all of progression, skill, and knowledge. Upon unlock, characters possess their entire…
positive · reviewer's own thumbsView post →Eh, it's a hard one. In current state I can't recommend buying this game. It has beautiful 2D desing, nice music, likeable characters, intresting post apocalyptic (I presume?) world. But core gameplay is tedious. It has a good idea: in limited time you have to find a way from room to fight the boss while collecting buffs and materials to spend in hub location. While it souds good, it has many problems: - Combat feels sluggish, you don't kill enemies fast enough to make it worth spending…

This has to be one of the weirdest camera systems I’ve used in a game. It feels awkward to control, and the lock-on makes it even worse.

Unfortunately, I can't say the same for the gameplay. The game feels too janky and unrewarding for a 1.0 release. Enemies having too much HP, insanely HIGH resources you need to spend for a level and skill and you have to worry for the in-game timer. I really hate the timer mechanic for this game since what's the point of having a quite sizable map with POIs and yet having…
