He should really lean forward when he runs since he can run so fast. Also, If you collide with a wall, he accelerates slower when you run the other direction. he kinda stops for a while.
It happened two times for me that i opened the game, ran straight foward, fell a little bit, and then the game just crashed. It happened two times out of four. Is this happening to anyone else?
edit. In the square bear screenies you have flowers out on the edge of the 3D boxes. Did you manage to make them move realisticly, and stay in place while the 3D box is doing it's magic?
