Blockout

Blockout is a 1-player arcade game for the TRS-80.

The player controls a character that continuously moves about a field, which leaves a progressively elongating tail behind them. The player can choose to have obstacles to dodge, or can play on an empty field. On easy mode, the player can see their tail, while in hard mode they cannot. There are 5 options for game speed. As the player moves, their score increases. At 100 points, a small ball begins to bounce on the screen. At 200 points, a bigger ball begins to bounce, that wrecks the previously laid out tail. At 300 points, another little ball appears, and at 400 points a large ball with a string attached appears, but when it hits a wall it breaks, allowing the player to travel through these breaks. For every 100 points, another small or big ball progressively appears.
