Accelcurve

Try to collect 100 green orbs without touching appering red obstacles. Choose smooth paths as they allow to preserve speed. Remember: you control only acceleration, not the speed. You choose whether to be "fast but inertial" or "slow but accurate".

WASD for acceleration. Z - for easy mode. X - for hard mode (100 red orbs already on the field). C - for endless mode (starts from easy). Escape to close the game.

The game has a built-in timer to encourage speedrun attempts. The field has a torus-looping geometry. Each time you eat a green orb a red one appears.
