Very nice! I'm not a fan of the control scheme - IMO Z should be undo (like, control Z) and R should be reset, with WASD mirroring the arrow keys.
The time loop mechanic is super clever, and I appreciate the over the top effect. I would have liked a few more levels, and more than one use of the feather box. What levels there are, however, are fantastic, and were a lot of fun!
