Doubleback is a puzzle game for the TRS-80 Color Computer, where players try to draw circles around objects for points.


In Doubleback, players are tasked with drawing circles around objects for points. Drawing around more than one object increases the amount of points given. The trick is, the objects disappear over time, and the player's cursor cannot touch the objects. While stationary objects are simple to rope around, some items move or exhibit erratic behaviors. Furthermore, drawing around a skull gives no points, and skulls also do not disappear over time.
