UpJumper

Experience a faithful tribute to the golden age of terminal gaming with UpJumper. Inspired by the classic ASCII platformers of the early 1980s, UpJumper brings the high-stakes, "just one more try" gameplay of the Kaypro era straight to your mobile device.

Navigate your character—the iconic lowercase ‘h’—through seven levels of increasing intensity. Scale ladders, traverse narrow platforms, and time your jumps perfectly to leap over rolling boulders. Every successful jump earns you points, but one wrong move leads to a plummet or a collision that costs a life.
