Really innovative idea and implementation of the theme! Took a while to wrap my head around it :D.
What I would improve is the movement. The jump should be a little bit higher and the friction a bit higher. How it is now it is a combination of your cool time mechanic and skill based movement. I think your time mechanic alone is great and this should be the main challenge and not perfect movement.
Besides that this is a really cool game! Congratulations!
