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.
another puzzly digipen student project. 20 levels in 5 packs, sandbox mode and the possibility to load user levels are unlocked from the start. levels are marked as solved, partially solved, etc. but level packs aren't, gotta keep opening them to see if anything's left to do. the rest of the levels aren't even shown until you solve the bonus goals, not even hinted at anywhere. I only found out there are more than 20 by looking at the install folder. it's a physics-based deal, and not just the 'look, gravity!' kind, reminded me of a bit of [b]the incredible machine[/b] and [url=https://steamcommunity.com/id/dohi64/recommended/241240]contraption maker[/url], its modern incarnation. you have all sorts of materials and other stuff to work with, collected in the grimoire as encountered. or not, as a bunch of them didn't unlock even after solving a level featuring them. the collection is only available in the main menu, unfortunately, and unlocked and locked items aren't different enough without mousing over. mouse-based controls with hotkeys to select tools (numbers), reset the level (r) and bring up [b]the menu (esc) that could use tooltips, just like the sandbox toolbar[/b]. place m…5 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

Much deeper than first impressions let on, I'm still trying to find a few things for the grimoire. The challenges are fun, but a little unforgiving. My children enjoy just messing around in sandbox, I enjoy it for the experimentation and the very non-traditional approach to discovery this game has. The fact that a pixel chemistry game has some deep lore going on in the background adds a little game within the game of figuring out the grimoire.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.
