Will O the Wisp

Will o the Wisp is a 1-player arcade game.

The player controls a small tank at the bottom of the screen that can only move a short distance horizontally due to surrounding mountains. The player fires vertically upwards, but can also angle shots. Alien ships swoop down and fire upon the player, and they must be destroyed before the tank is lost. One hit destroys the tank, and the player can lose 3 tanks before the game is over.
