You missed opportunity to have confetti come out of the final white dispensers...
That aside, this was a fine little puzzle-platformer that could have been just a little better in pretty much every area. The controls could have been a little tighter, the visuals could have been a bit more detailed, and some music would have been nice. I also would have liked if the "press escape to pause/restart" tip was a couple rooms earlier since there is one earlier where you're still able to fail. Still, the game does tie into the theme very well.
