Thanks for the bug report :D It really isn't that smart to base the Character Flip onto a single keystroke, when the movement's just takes the Horizontal Input, which includes everything. I should have based it on the x velocity...
Would be nice if you could check out my submission aswell (if you havent already)
Ah! German as well I see... ;D
yah, a friend of mine exported the game, and didnt have the engine set to english :P
