The puzzle is unique and easy to learn, but also complex and fun.

I’ve sent an email to developers but they aren’t responding. You can’t get to the last set of puzzles without purchasing additional color key. Why not just charge for puzzles, rather than put in a fix? Level 151 will not accept any response.

This is the one game I replay over and over again. If not for the mind-bending puzzles, then definitely for the beauty of its animations. I love every bit of this app.

This game you can tell is designed really well with a good and simple user interface. Tricky game but kept me coming back!

Great app! Very challenging BUT I was so disappointed when I finished all the levels 😢

I got this game years ago and kind of went back to it when I was looking for something beautiful, rewarding, and easily distracting to fall into id go back. Just finish and I’m equally happy and sad there’s not more!

This is the best free puzzle game out there! No ads, just chill colorful puzzles with color accessibility variations!

If you like puzzles, this is a good app to have.

Highly recommend

i love this game i just wish it updated with more puzzles more often :/
