About this game
Commander Keen in Aliens Ate My Babysitter! combines platform exploration with a pogo stick and a neural stunner. This archive runs the demo documented in K6DEMO.DOC. Levels can end at an exit sign or after finding an important object, so exploration is part of the task.
Left and Right move, Ctrl jumps, Alt toggles the pogo stick and Space fires. Hold Up or Down to look farther in that direction. Up also enters doorways and climbs poles; Ctrl lets Keen leave a pole. Holding Down while pressing Ctrl drops through a narrow platform.
The pogo reaches higher but is harder to control. You can deploy it during a normal jump, and Keen can grab ledges before pulling himself up. These movement options make apparently unreachable places worth revisiting. The manual also describes optional two-button firing with Ctrl plus Alt; the table uses the ordinary Space firing default.
