Checkpoint 2: Attaching the "asteroid" to the player if the player touches the "asteroid" This part was challenging as there were new commands I learned while trying to incorporate the retro lab componemets. I included the "asteroid sprawner" to get more than on "asteroid" on the screen. The next part is to end the game.
