main things i fixed was the stopping when he hits the mouse pointer took the longest to do secondary things-his lag when it started that random position change did some things to the asteroids made the code more effecient and did some costume changes not much i don't work well in bitmap and added a start button a random spawn rate breaking motion and i also changed the backdrop colors fixed the grounds never showing up problem and i fixed how when the start goes up it hits the top and stays there so i made the process with less steps so it runs smooth I also fixed the placement of the sprites in their costumes imoved them so it would run smooth with the mouse and so when you turn around there is not too much of a movement because of difference in the costumes direction and the mouse
