Recent verbatim reviews from Steam — separate from playze.io community reviews below.
While it's a cute little game with an interesting concept, the vibe coding is veryy noticeable. It might be fine if the dev actually fixed anything but they seem to unwelcome negative-ish feedback. There also isn't any signs that the game is still being updated :,< I really want to see this game improve but as it is currently I can't recommend it7 found this helpful
I am so upset I was having a lot of fun with this game and then I found out that it uses AI :'c Wish I could get a refund but I played more than 2 hours. If you don't support AI be warned.6 found this helpful
I purchased this game while it was on sale and missed the fact that this game was made with the use of AI. While the art work is cute, i love the idea of a rattery game where you can breed and raise a bunch of rats and do things with them. I can see where the AI infiltrates and it's disappointing :// It has been a mini hyperfixation but like other reviewers said, - there is no way to pause and look over your rats and have to have the game active and "playing" in order to do anything. I'm someone who likes to look at every page and part of a game, family trees, genetics, etc. and take my time doing so to make a plan of what to do next. While you can put the game time on "epic" time still passes which can lead to rats aging, dying, doing x thing (even if it happens slowly). The only thing you can view while paused is the wiki. So if you wanted to organize your rats or figure out their stats and who is bested matched while who time still passes. - when using the "breeding" tab to breed rats it is frustratingly hard to see the 'male rats', 'female rats' and 'pedigree' sections of that page. I have to use larger text and instead of making it understandable it is like your writing in…
The Rattery game of my dreams! This game filled the VirtuRatz-shaped hole in my heart. It has accurate genetics & inheritance, adorable pixel art, and satisfying game loop of upbreeding my rats to higher show quality. I love the level of customization that the settings allow. There are a few things that would be nice to have added such as: - Agility Shows (+ stat breeding) - A memorial section for my favorite rats that have passed - Treats & Enrichment* (optional, leans more into pet sim territory)
it supa dupa fun. I love it.
such an adorable and fun game so far!! im a bit sad there aren't any recent updates, but i love it either way <3
