Very nice start to a simple platformer game. The jumping and movement were fun to use, all the enemies were clear. However, once you get to the bottom area, I could not find a way to return to the top, the vertical attack is useless against the crystals that are in the air. The graphics are nice, some animations would make it even better. I didn't understand the story or reasoning of why I am picking up acorns and crystals and why they heal me, but I still played it for a little while and enjoyed what I played :D. I hope to see it with some more content and polish in the future! Great job on completing a game for the jam.
