I have started to work on a jump and run game.

thx for any comments. 
Basic but nice, but why are the controls so hard?
Du solltest die Seite vielleicht auf Englisch anbieten…
I like the character and the smooth camera movement, but the controlls are very frustrating, I barely couldn’t move that guy.
Und ja, du solltest die Website auch auf deutsch anbieten 
controls are fixed now - I should also offer the site in english ;D
Danke fĂĽrs ausprobieren!
Yeah, it’s better now. But now its maybe a little bit too sensible ^^
The jump is really wierd. Why is he gaining velocity as the progresses upwards in the air? It feels odd. Try doing that the other way around, so the jump will have a nice curve.
