Inferno

A maze/shooting 'em up game with a maze layout similar to Crystal Castle. You walk around a 3-Point Perspective maze with 4 directions to shoot your enemies. When you shoot the enemies, a dark soul is released and runs away to the monsters mouth. You must touch the enemies soul before it gets to the mouth or a regernerated more difficulty enemies occurs.

The game has 99 levels and it's endless. After 99 levels, the game is restarted to level zero. It never ends. After wave 11, the game repeats from wave 7 again. The difference is harder difficulty.
