I'm trying to re-create the behavior of the game in the gif, having my character in the middle, but I'm trying to reduce the game frame even to an only one point (look at the attached picture) and character is still moving in all directions. Maybe what I should do is to set the character in a fixed position in the center and move the background, but anyway in that case I need my character to be able to rotate. Anything that could help me? Thanks.
