What an adorable idea for a game. My wife and I are expecting a girl and I would love to be able to do something like this for her one day. I ran into a bug when I came back home after defeating all the creatures, but other than that it was a fun game! I bet your daughter loves it. 

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.

Great game! I thought the concept was very cool, having to collect all the colors.

A lovely game, your daughter must be thrilled! I like how getting the rainbow ray made me able to do so much more, that really works for the There and Back theme. During the boss battle, though, I couldn't seem to move or do much of anything so I died. Is that part just unfinished? My only other criticism is that the high pitch of the jump sound effect hurt my ears after a while.  Overall, though, the music and effects are expertly chosen. My favourite part is how you animated the main character sprite. You truly brought that drawing to life! You and your daughter might enjoy trying my entry, 'Hurrah, Hurrah!'.  I'm a parent, too, so all of my games are designed with families in mind.
