Great animation. And the movement feels really good too. I like the premise, but the one hit death on the enemies is very frustrating.
I think I have to tweak the hit boxes a little bit, so it's more forgiving. And probably also change from insta death so you only loose time/life when you hit an enemy.
Edit: Finished level 3 with almost 2 minutes to spare. Would definitely play more of this. Specially levels that focus on forward momentum, like level 1.
