Arrow keys to move the character This uses no pen tool or rays and it is a collison test for me, go to the grey button, the grey button will make the red square green as u stand on the grey button and when ug o off it turns red again the blue thing is the middle is the collison its like a wall try to go from any sides and you cant get inside then also y to unable the hitboxes and x to enable the hitboxes.
