A paper airplane. A house full of danger. One way out.
Glider is an action game for the Macintosh written by John Calhoun (Soft Dorothy Software). You pilot a paper airplane through the rooms of a house, riding updrafts from heating vents and avoiding everything else -- bouncing basketballs, dripping faucets, popping toast, enemy paper planes, and the family cat. Each room is a side-view cross section. Get through the last room and you escape the house.
