Uses the force of gravity to do what it does best: send projectiles flying around in circles until they kill something. Gravity Game is a fun, 2D shooter where you can either orbit planets or land on them. No matter where you are, you'll be shooting.
Once you get the knack of gravity, the game's relatively easy. WASD moves you around, and you can shoot by left clicking. Your projectiles will orbit the nearest planet.
Use gravity to your advantage. It's what it's there for after all. Use a planet's pull to avoid projects, or rocket yourself out of danger.
