After escaping from a series of Möbius strips, the one-sided shape from One side, one jump finds herself in an infinitely-long plane. However, someone painted a question mark on her, so a speedrunner mistook her for an end goal. Fortunately, this plane lets her jump as many times as she wants; unfortunately, jumping is the only thing she can do. How far can she go before the hero catches her?
I made it for eevee's Games Made Quick Four jam, with the theme "the faster you go, the longer it takes". (Also some aspects were inspired by nmccoy's Wavespark and Sonic 3.) This is not as polished as I'd like, so I'll probably make a few changes a bit later. Developer's commentary
Controls: press any key or tap anywhere to jump. Hold down the jump button to bounce; press jump in mid-air to activate powerups. P to pause. Use the terrain to build up speed. Manual
