is not jumping, is intended like that, if u look, is when he steps with the right leg, which usually is more powerful, its cos is a sketch that i didnt bother to smooth the animation... also a and d or ok, cos u gotta imagine obstacles coming at the same speed then the background, more speed would make it too fast for my idea, and a is slower, cos, although u dont see it there, when pressing a the ninja would look backwards, and would just deccelerate a bit for whatever purpose, is not intended to have the same speed than going forward, but thx, it will take me lots of time to finish this, cos i just began learning programming, but when its finish u tell me if u like it
I planned one more sequel, so it's not the end of the story.
