It seems the destroying of all sprites of type Player in the clear all function messed up something regarding collision, don’t know what:

I also removed any occurrence of controller.move sprite, since it made the Player move awkwardly.

**Destory all sprites of kind Player** will remove the self sprite (Me in your project) from the phisical engine. Remove this block, walls will work.
