Space Stairwell

Space Stairwell is a survival arcade game in which a sphere climbs an endless series of rising platforms. Each jump uses energy, so progress depends on choosing platforms while also collecting items that recharge your supply. The aim is to survive by completing the available levels as the climb continues.

Higher levels demand quicker reactions because platforms collapse faster. Jumping to the right platform is only part of the challenge: you must also manage energy and respond to the changing pace. Completing one level unlocks the next, giving successful platform choices a direct effect on your progress.

On mobile, tap the platform you want the sphere to jump to.

On PC, click the destination platform with the mouse to jump.

Use A and D or the left and right arrow keys to slide.

Collect recharge items so jumps do not drain your energy completely.

Reach the required platform progress to complete a level and unlock the next one.
