Really cool game, I really enjoyed playing it. It took my a while to get the timing right with the eye animation, but once I did, it felt really good to play! I also liked that you had a lot of checkpoints around!
Sometimes, idk how, when I switched the eye and I was stuck inside a block for a short time, I was floating above the ground a little (dying fixed it). I also think the game would benefit from some background music.
Over all really fun to play, I played till the end :]
(I hope you make it to the 20 ratings :] )
