Move your mouse / drag your finger left-right (or use arrow keys) to tilt the platform and roll the ball. Don't let it fall off the ends or drop through a hole. The platform shrinks and holes appear as you survive longer.
Tilt Balance is a free hard online physics game: tilt a narrow platform by moving your mouse to keep a neon ball rolling safely on top. The platform slowly shrinks from both ends and random holes open up over time, forcing constant, precise micro-adjustments. Score is the number of seconds you keep the ball alive, and staying in control for a long run is what makes this one of the hardest balance games in a browser.
