Excellent game, I like the aging mechanism and that you actually have to use them to get through, so a platformer with a hint of puzzle.
When I jumped from up high, I somehow ended up inside of one of the platforms and needed to restart the whole game. I think that might be because of the Rigidbody collission (if you used that) I think it was collissionDetection that helps with that :)
Anyway neat game and perfectly made for the theme 5/5!
