This game has a cool sounddesign, which the guys apparently did themselves - my respect! However, the heating mechanics, in my opinion, is not fully thought out, because it doesn't push the player to do anything else but just stand still and cool down. Probably need some kind of motivator in the form of running enemies that would make it impossible to stay long.
Either way, I think it's a great start to developing a full-fledged platformer game!
