Swipe Lab

Flick the arena to roll the ball. Sliders update live — no restart needed. Settings are saved locally so you can come back to your in-progress tune.

Strength

Multiplier on px/ms swipe velocity. Higher = each flick pushes harder.

Per-flick cap

Hard ceiling on a single flick's impulse magnitude.

Accumulated cap

Total pending impulse from rapid stacked flicks.

Thrust decay

Per-frame multiplier on remaining flick energy. Lower = snappier, higher = longer push.
