I really enjoyed this game. It reminds me (a lot) of the game "This is The Only Level" but with its own twists, which is great!
The mechanics are solid and while the graphics are simple, they are really enjoyable (love the animation of the little box).
I have one criticism though: while it's fun to see its previous bodies, the fact they are still physically interacting gets very annoying, I quit at level 18 because of it.
But very solid entry :).
