X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=c572ff4247c9107091c2b526721a2befb32f0ed1;p=supertux.git

implemented double jump (press up again while jumping) and hovering (press and hold up while falling down)
both need some tweaking (especially when jumping off enemies) and should of course be triggered by special items in the final game
