Tuning input so movement feels immediate and predictable.
Immediate response
Update position as soon as input arrives; apply smoothing only for visuals.
Predictable velocity
Start with linear movement; introduce acceleration curves later if they improve control.
Mobile drag scaling
Move relative to finger delta, not absolute position, to prevent jumps when the finger re-engages.
Keyboard parity
Support Arrow keys and WASD; ignore repeated keydown events.
