The player controls a small character who moves about in a variety of chambers, and can fire in 8 directions. In each chamber, a number of monsters appears, and if the player destroys them all, they gain warp access to nearby chambers. A map showing how chambers align and the player's position is shown in the top right corner. After all monsters are destroyed, new dangers flood the screen, and the player must quickly leave. The goal is to reach the chamber highlighter red on the map. The player starts with 9 lives, and it's game over when all are lost.
