Critter © 1980 Bilbrey, Brett.
This program will place a Space Invader-type 'critter' on the screen that will bounce around from top to bottom and side to side without disturbing anything on the screen. His speed is controlled by hand control #1. This is a machine language program that uses the Bally/Astrocade's Vector motion routines that contained on the on-board ROM.
Rleased in December 1980
