What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Players praise this physics-based puzzle game's depth and creative sandbox mechanics, comparing it favorably to classics like The Incredible Machine, with appreciation for its experimental discovery-based approach and well-implemented physics interactions. However, critics point out frustrating design choices including tedious pixel-searching, unintuitive progression (hidden levels only unlocked through bonus goals), and unforgiving difficulty that drags out what could be a short experience into a slog of tedium.
Its short, weirdo and not that fun e-e But as i try mostly everything well o-o Still recommend by some reason q-q2 found this helpful
It's a fun game. The cell "physics" are pretty interesting and leave room for a lot of variability. Some puzzles require you to think pretty hard about the solution, and others are just super fine-tuned it's not necessarily "thinking" that's most required, but very quick and very precise movements. So I'd say it's an imbalanced game because of that. Also, considering everything the game possibly can do, it *really* needs more levels / level packs. It felt like I was just starting to get the hang of it (and enjoying it quite a lot), when the content ran out. I hope the dev expands on the levels at some point as I'd be happy to come back to the game and play more levels!1 found this helpful
The name, the pitch and the tutorial levels led me to expect a clever puzzle game built around different material combinations and interactions, but the actual puzzles are much more about guiding generic materials across generic landscapes, with the material interactions serving as singular gimmicks, like perhaps water getting converted to steam then back to water halfway across its journey. I'd prefer to rate this as neutral and if I were grading it as a student project I'd call it pretty good, but does it stand on its own merits? With all the puzzle games out there, is it worth checking out this one? Not really.1 found this helpful

A great free game. Around 2 hours worth of puzzle solving, and way more that I haven't experienced even after you finish. The visuals are great, the music is great, the interactions between different cells are great. Apparently it also supports modding/custom level packs?! I have only a few issues. Firstly, there is a lack of hints or assistance for levels that players get stuck on. Also, there are currently 0 listed guides for this game, so I'll probably make one. Secondly, the background and foreground are sometimes hard to separate mentally, and i'll confuse the background as being interactable and the foreground non-interactable.
fun and gives purpose to the whole 'pixel physics' thing.
