Submania
Description
Submania is a 1-player arcade game for the TRS-80 CoCo.
The player controls a sub that moves in all directions, and can fire vertically and directly forwards. Red and black mines continuously scroll from the left. The player can shoot and destroy red mines, but black mines are invulnerable. Red mountain bases on the surface need to be destroyed, and white crosses fall from the sky that must be collected. The player starts with 3 lives, and loses a life if they hit a mine or miss a cross or base.
