Very nice idea, I love the concept !
It is a bit tricky to get the good timing but once you get it you can fully enjoy the game. And the new mechanics are explained with a kind of tuto level that is nice to have.
The animations and sounds are very nice too ^^
I was glad I could finish the game because I had a hard time on one of the last levels and nearly gave up ^^'
That's a great work you did, simple but fun !
