Space Mouse

Description
Space Mouse is a 1-player arcade game for the VIC-20.
You, as an interstellar Space Mouse, find yourself trapped deep underground on an alien planet. You must weave your way upwards through the cracks in the rocks, avoiding the space cats that dig down. The Space Mouse can move left, right, and upwards through cracks. If the mouse collects a super cheese, they gain enough energy to burrow through solid rock for a short time. As the mouse moves higher, space cats approaches faster. The player starts with 7 lives, and has limited oxygen to travel as far as possible per life.
