Your sound and art work is great. Very responsive controls. The double-jump is a bit finicky, however, as I'm still not sure whether it only activates when the player is overlapping a wooden beam, or if it also activates in mid-air. It would be nice if key bindings were accessible in-game (and not just from the main menu). Curious how the drop system is implemented - for tougher enemies there should at least be some sort of drop (i.e. I felt cheated getting nothing after defeating a big red dude in one run; while being richer by simply killing a few bats in another run). Looking forward to more updates.
