I thought that the game was pretty fun and found myself playing it for maybe a good 5 - 10 minutes. at first I was restarting the level every time I messed up because I didn't know about the undo button, but maybe that's just my bad. I think it might be nice to make important elements stand out more with maybe the red color of your color palate. the game was fun overall though and I enjoyed playing it! good job!
