haha this is so funny! I love it i made me laugh out loud :P really love the theme so switch between ages and the effects of this. really nice! I could not resist so go back to the grownup for faster movement but making the game more challenging because of it. Great idea for game-play. But i was not a fan of the control's it was all the much together i would have gone for 2 handed play instead of try to put everything there for your left hand, since playing with wasd is the norm these days.
Like the art style and graphic! some people seem to pick pixel art just because they like it, but here it fits the game perfectly :) so good choice i would say!
