Space Stairwell

Space Stairwell is a fast-paced survival game. You control a sphere and must jump up an endless series of platforms rising from the bottom of the screen. The goal is to survive as long as possible by completing levels. Every jump consumes energy, so you must collect items to recharge. The game gets harder in higher levels, with platforms that collapse faster and require quicker reflexes. You can unlock new levels by successfully completing the previous ones.
