Great approach to the topic of the jam - I really like the mechanic with manipulation of your and environment age. Plus for making levels resemble locations which were part ofg characters past - nice touch. Meddling with mechanic was fun, though it lacked some kind of proper tutorial, but you still could figure that out later. Also, the soundtrack was amazing and I really wanted to hear the theme playing between "waiting room" and next set of levels more than in that passage, it was great, sadly, there wasn't a lot to do there other than shoot at walls like maniac while listening to music.
Anyway, that was great experience and I would be actually willing to see some kind of enhanced version of this game, if you will ever feel to polish it more.
