Time Tunnels

Time Tunnels is a 1-player space-themed arcade game for the Apple II.

The player travels through a number of progressively more difficult time tunnels battling alien creatures. The player controls a spaceship which can move clockwise or counterclockwise around a large rectangle. The ship fires towards the opposite side of the screen they're facing. Numerous alien creatures and vessels move about the screen, some of which travel along the outer rim of the screen following the player. The player has a limited number of teleports, which are represented by an hourglass on the right of the screen, that allows them to move to the opposite side of the screen. Care must be taken, as the player can shoot themselves while doing this. The player regains teleports as they complete each level. The player starts with 3 lives, and it's game over when all are lost.
