Well. I've been working on this since I added a second level to my game. When you go from level 1 and level 2 and did not kill all enemies on stage. They stay on stage and the new enemies (I believe I removed this temporarly) are added on top of the old.
The enemies in my game are stored in an array called enemyList. I've tried emptying it, but it didn't work. I've tried every method that I could think of, so I came to the forums.
My current game code (Doesn't include the class files for Enemy, Bumper and Bullet):
