GravityTank

Drag on the screen to place a gravity point that pulls your tank toward it—the farther the point, the faster you accelerate. Tap to fire your cannon at enemies. Release your finger and the tank coasts with inertia. You get 3 gravity flips per run to switch to repulsion and push the tank away for emergency dodges. If you keep pulling the tank with gravity for 5 seconds straight, a 3-second Gravity Storm activates, bending nearby enemy shells off course. Each kill is worth 1 point, with +1 bonus during Gravity Storm. Levels have no time limit; the game ends when health reaches zero.
