This is amazingly well polished. The aesthetics are nice, the animations are smooths are the sound design is clean. The jump mechanic adds a nice twice to the classic platform type game. 

The difficulty seems rather high for a gam jam, and the game is defintly resisting, but this is not a bad thing.

If I had to to find a point where it could be improved, it would be in way the theme fits in the game. The game is definitly heat-themed, with the lava and stuff, but the gamplay mechanics do not feel to be that much about "overheating". 

Thats what she said.

Nice game btw, I like the difficulty change as the levels go farther

Cool game! Had fun with it but many times if you fail a jump it just means death. It also seems that you always just need to charge the bar to the max.

The graphics and animations are really great, just wish the jumping was a little more responsive, other than that, really fun game :)
