SNAKE — classic snake for Xiaomi Watch S4

Classic snake on a 16×16 grid rendered on the round 466px screen (320px board, 20px cells). Swipe to steer; the crown is NOT used (confirmed unsupported by the Vela quick-app API on this device). Tap the overlay to restart after a crash.

Status: RENDERS AND PLAYS ON WATCH (user-confirmed since 0.2/0.3).

Controls

• Swipe in any direction to turn (180° reversals are blocked in the logic)
• Tap the game-over overlay to restart
• Crown does nothing — no rotary API exists in Vela quick apps (triple-confirmed against docs + the largest open-source S4 app)

Version notes

• 0.2 — board renders on watch (user confirmed); ring undersized
• 0.3 — designWidth 480→466 fixed the undersized bezel
• Crown-based input was tried and disproven — swipe is the only reliable input
