No gravity — you're in full control. Your missile climbs upward while rocks fall toward it. Hold left or right, swipe anywhere on the field, or use the arrow keys to steer. Most rocks are large and stationary; smaller ones drift sideways, speed up and slow down, or move diagonally. Watch for the glowing green power-up — grab it for a temporary speed boost. Things start slow and get relentlessly faster. Reach 999 points to win — very few will.
