VERY BETA-ISH http://www.yoyogames.com/games/159880-jump-game-beta
I made everything in it except the health bar. That was tricky.
Do I need to show screenshots even though there are two(incorrect*) already there?
Problems to fix:
-Not stop when player touches walls
-Not stop a few pixels above ground
-Not get stuck to enemies (Hard to fix)
But yeah, it's mostly me who has made the game awesome

Enjoy!
*The screenshots I take of the current game don't show up anywhere... o_O weird...
