Ratings and reviews

Fun for 99 cents on sale, that's it. The developer seems to have discontinued updates since 2015. The community still uploads plenty of creations to see. Only problem, which is INCREDIBLY bad, is the only way to find creations is to browse pages of creations by date. No way to look anything up. No favorites to save to go back to. Just start at the most recent and click click click backwards through history. Quite awful, and almost defeats the purpose of having a community.

This is so much more entertaining than I expected. There's plenty to do, and it's all very satisfying - both aesthetically and in feeling. The only thing I feel is missing is a mix option to move things around, and gyroscopic tilt would add a little extra something - but frankly they're not needed. I've only played an hour or so but so far it is wildly fun. IMO it's well worth the money, I got it on sale but knowing how good it is I would gladly pay full price for it. 5/5 would recommend.

Not a bad pixel game. It could definitely use some updates though, the gui could be more descriptive and in depth. For example the share tab could have a search bar to look for specific levels, maybe a filter button. You could add more tools, like a clone tool (not the clone emitter) that can copy pixels you drag your finger over, then a drag tool to drag pixels around the screen to make reactions easier (and more fun), and an identify tool (in case we can't figure out what type a pixel is)
