Using rects?
I believe that using rects it's the same thing with using image.
If I am not wrong Max2D does not store the rotation values for evry rect you may use but stores the pixels in the COLLISION_LAYER... So it doesn't mater if you use rects or images.
Maybe Rects are faster for the moving objects because they take less time to be added in the collision layer but for the static use images and load them just once before the main loop in a layer that you will not reset with the collisionreset Function.
