Roller Controller

Roller Controller is a 1-player arcade game for the TRS-80 CoCo.

The player must guide rolling marbles from the top left of the screen into the proper bins at the bottom of the screen. The solid colored marbles with a "T" in their center must fall into the bin which is the same color as the ball. A "ringer" ball will also appear, which is a combination of the three colors of the other balls. The ringer balls must fall through one of the two funnels at the lower right and left side of the screen.

The balls are guided to the appropriate bin by opening and closing the trap doors at just the right time. At the extreme bottom left and right of the screen are two fans, that will blow balls back up to the top of the screen, and start over. Each time this happens, the velocity of the ball will slightly increase.

In the top right of the screen are happy and sad faces, which represent how many balls must be correctly or incorrectly guided into bins before the game is over. There are 3 skill levels.
