Unlimited lives:
Enter the African Mines without a key to be transported to Transylvania. Climb the mine car tracks and collect extra life. Warp out of Transylvania without the key, and repeat the process.
Hint: Defeating the Moon Boss:
When fighting the Moon level Boss, the mouse, go in the middle and keep hopping in the middle of the screen. You will usually kill it before it can hit you. It will flash repeatedly from the first time you hit it.
