I like this simple, little puzzle game. It takes mere seconds to learn. Is relatively easy, and thus pretty relaxing. Yet still of a difficulty that will keep you thinking on your toes. Level length is generally perfect for when you only have a few minutes to play. But the game will keep you entertained if you have a long time to waste, as well. I read several complaints about colors looking too similar. I think that's just part of the challenge, and it's not all that bad. I appreciate it...

Experienced some bugs, and even the bug report bugged out. After the third time I gave up. Also, the levels are way too easy at the start with no apparent way of skipping some stages.

Make the colors.with proper contrast! I mess up so many levels because "this red" was a little bit different from "that red", that's incredible. Just make different colours, this is so easy!
