I ran into the most amazing glitch while playing the game. For some reason when I jumped after the character starts to talk about the blob thing stealing all the colors you rocket off into the stratosphere. Like unable to stop moving upward rocketing. If you do it once, every time you jump after the same thing persists. Restarting does fix the problem. However using ctrl to fire when you get the rainbow power is not greatly signposted. Apparently my audio driver crashed right before I went to play this game. After giving the music a listen it sounds pretty good.
The art is all well done however most of it not being created for the jam, the touch of using your daughter's art for the main character is pretty cool however. The one issue I do have is that while the blobs sucking the color out of the spaces they inhabited is cool, when they fire black little projectiles it makes it much harder to tell them from the background. I also had a problem with the boss fight being unable to move and being killed due to it.
