Latency & Controls That Feel Right

Great controls are invisible. Use these guardrails:

1. Immediate feedback: update position as soon as input arrives, not at the next physics tick.
2. Predictable acceleration: use linear velocity first; add easing only if it helps.
3. Mobile drag: scale finger delta rather than absolute position to avoid jumps when re‑grabbing.
4. Keyboard parity: map A/D and arrows; ignore repeated key events on keydown.

Test on a low‑end phone and a high‑DPI laptop—both matter.
