Typical AI generated 2026 game, except it's from 2025. Mouse sensitivity is overclocked to 999%; it's not only not set to borderless by default but there just is no borderless mode because they've never played a game in their lives; the mouse wheel goes through items in the wrong order; the refresh rates are sorted like "165, 60, 144". Out of the Viscera Cleanup clones I've played, this is the least inspired. It takes random mechanics from others and bumbles them together. To expand on the mechanic where individual gibs make everything dirty if you're not careful carrying them, here there's color-coded types that can explode into more tiny things to deal with. Not handing out any originality points for that one I'm afraid. As expected the game is missing essential features like a scan for dirty areas, showing which parts of a level are cleaned and which are not, etc. On the plus side, the multiplayer mode either got some testing or works thanks to sheer one-shotting luck. So as you're not having fun, you can at least not have fun with your friends. That's something. And they don't expect you to put the garbled furniture back (or keep it intact, for that matter), so it's relativel…15 found this helpful
I can't recommend this, usually I like these sort of games because they scratch an ADHD itch, but this one is lacking. You can complete every level in a couple of hours, the only real incentive for me to keep playing further was to unlock achievements, several of which were bugged and couldn't be unlocked without exploiting another bug. For a game that's been out for almost a year, there's too many bugs and not enough content.7 found this helpful
you know you're not off to a good start when the tutorial has a bug that required me to smack the monster to get it in to the cuboard as apparantly i cant pick up traps when its caught somthing, Immediatly afterwards i was faced with another bug where i was holding an invisble trap with no way to swap what i was holding, this bugthen progressed to being unable to go to the main menu and the HUD dissapering. And considering how long some of these levels look like they will take, im not going to try carrying on wit hhow buggy this game is. you should be ashamed to release such a game in this state3 found this helpful
In the 18 years I've been on Steam I've never requested a refund for a game. I ended that streak today with this game. I've also never left a bad review. I purchased for myself and a friend to play co-op. Looked fun and I like the concept. It was unplayable and glitchy. Major issues with the game make it game breaking. Tons of bugs. - The game crashes immediately when you try to exit co-op and choose a new level. - Upstairs rooms are often missing the floor so you just fall through onto the first floor. But when you look up the floor is there as the ceiling. - There's often incrdible amounts of lag. - Mouse sensitivity is insane for some reason. - Random bugs make the game unplayable. - It's very difficult to even manipulate objects. Give this one a skip.1 found this helpful
