Tweak it

  • Increase speed: change the tick = (tick + 1) % 5 throttle to % 3.
  • Walls instead of wrap: remove the modulo and end game if head is outside 0..cells.
  • Change colors: edit the fillStyle values for food/snake.

    • Key Takeaways

    • ✓ A render loop plus keyboard events is enough for simple arcade gameplay.
    • ✓ Small constants (speed, colors, grid size) dramatically change feel.
    • ✓ Wrap vs walls is a single condition change.
