About Gravity Ninja
In “Gravity Ninja”, you take on the role of an incredibly skilled ninja, on an exciting journey full of challenges and unbridled action. In this game, gravity is not an obstacle, but rather a tool in your character’s nimble hands.
How to play Gravity Ninja
There is no tutorial to sit through — the game explains itself. Keep a hand on the arrow keys / WASD; everything else is listed in the controls table. It is built tall rather than wide — comfortable one-handed on a phone, centred and uncropped on a monitor. If a round goes badly, restart — attempts are cheap and it is usually the fastest way to improve.

Why it is worth playing
Plenty of adventure games want a tutorial and ten minutes of setup before anything happens. Gravity Ninja does not — it is playable from the first second. It earns the replay rather than demanding it.
