Okay, this game looks and sound awesome!
And it plays really well, too! I thought about making a Platformer, where the player doesn't control the jump but I just couldn't think of how to make it fun. The idea to show the player when this jump is going to happen is simple, but genius!
And that you have different worlds with different aesthetics and their own mechanics is astonishing. Very good job overall!
The only thing is that the game is a tad bit tough in my opinion, but a whole lot of fun.
