Cool little puzzle game,
the music is quite fitting and relaxing. and you really have to think about some puzzle twice before you solve them.
There was a minor issue, the rewind(nice idea for rewind animation btw) is a little bit clunky.
I really hope you had fun making it, because I had fun playing it.
Ohh, and PS: there is a minor bug: you can actually just push that block, that blocks your way into the goal and win the game like this ^^"
