This game was great fun! What really made this game great is the sheer amount of levels and content, I also like the difficulty curve, as it does get quite hard, but it has an excellent learning curve.
One problem I had was when I died I instinctively pressed R to reset, but it reset me twice then, and often I had started moving after the first reset, so I had to reset a third time.
Especially in this game jam setting, a game like this is great! Good job.
