This is a really fun game, I deffinetely enjoyed playing it and the punishing design is really appealing to me, for it just made me want to play more and more to see if I could surpass my last best. The music was appropriate with the theme, and the sounds were pleasent and fitting.
On the negative side, the player seemed a little to fast and the controls somewhat imprecise, and I think the pop-up event should only appear when the player is on the ground and that it should not have the last input to still move the player.
All in all, with controls a bit more precise this would be a great game, even though it is already pretty good one.
