Super fun game and it felt pretty intuitive to control. There's definitely a big jump in difficulty with the spikes so I would warm up to that a little more but overall the levels were all super fun. There's definitely room for shortcuts and I had a good time trying to find some. 

Fun game, very difficult but satisfying to beat. Controls were pretty intuitive and movement is fun. The level design was good, but I think it would be worth having some easier levels before 2-4, as they jump pretty dramatically in difficulty before you can get used to the controls. The spikes feel a little bit punishing given that they immediately end your run; maybe they could deal a set amount of damage and bounce you back a bit, reducing your limited time instead of just ending the game.

Soo, its cool (pun intended), but: The UI is kinda bland, When you get smaller you cant collect coins, no button to instant reser (r for example), the theme is green floor but it very vell could and should be ICE, the rotation happens too fast. The fire pits seem to be unavoidable, and they take way too much HP, i cant pass level 2. 

Edit: i took a different route, gonna finish the game.
Edit2: well the game is too hard for me and the music makes me dingle

good job, the use of the theme here is pretty cool, nice :)
