Ability to undo would be really nice.
Also at least in level 10 two of the very closely matching colors are put in the same orientation which makes it even harder to distinguish :)
Good job!
Decent game with very hard puzzles.
Also it is incredibly annoying that you have to turn off the music on each screen, (and when dead ) and that you can't turn of the sound effects.
Probably a good game, bunch of bugs, and bad Kongregate integration. I can't see the full window on kongregate ( google chrome ), first level does not complete even with full distance
