Zaxx

Zaxx is a 1-player arcade game for the VIC-20.

A small spaceship moves across the screen from left to right, moving slightly lower on the screen each transit. The player can fire directly downwards, and tries to shoot enemies at the bottom of the screen. A number of alien ships appear at the center of the screen, and block player shots. The player gains 5 points for every enemy destroyed. These ships can temporarily be destroyed by shooting them. If the player runs into enemies or blocking ships, it's game over. The player starts with 99 missiles, and regains some of these for every level completed. When all missiles are used, it's game over.
