Coin Dash · timing upgrade

Collect all six gold coins in 30 seconds. Avoid the red triangle. Start, focus the game and use arrow keys or W/A/S/D. On a phone, hold the direction buttons.

Ready. Press Start game.

This version preserves up to 0.1 seconds per rendered frame in small updates. It does not increase rendering FPS; longer stalls still drop time deliberately. Compare the original version.

Switching tabs or leaving the game pauses it and clears held input. This is a visual game; target-device and assistive-technology testing is still needed.
