Space Stairwell
About Space Stairwell
You control a sphere bouncing upward through an endless column of platforms that rise from below. Your job is to stay alive by landing on each platform before it vanishes beneath you, collecting energy pickups to fuel your jumps—every leap drains your reserves, so missing a pickup can end your run. As you clear levels the platforms crumble faster and demand sharper timing. Poki Games hosts this reflex challenge where one miscalculation sends you tumbling into the void. Unlock tougher stages by surviving earlier ones, testing how long your reactions hold out against the accelerating chaos.
