Space tower, where the player controls a neat spherical CPU. Drag to move, hold to stop, charge to sprint. In danger, hold nearby hackable machines to make a way out.
On the other hand, the tower is full of various crises. In addition to the need to avoid falling from high places under normal gravity, area attacks of different types of damage such as lightning strikes, fire and freezing will appear. As the story progresses, you will experience low-gravity or even zero-gravity space, and the difficulty of control often overturns your feel that victory is inevitable.
