  1. The C2 screen has a 320 × 142 rendering area, with the corners masked into a rounded capsule shape. Tell the Web Driver to keep important content inside the safe area
  2. The C2 has limited display refresh bandwidth, so avoid moving too many elements at once
  3. The C2 screen is not designed for rich color reproduction, so a black game background is recommended
  4. C2 includes a simple physics engine. Tell the Web Driver to use the built-in physics engine to implement ...
  5. Avoid game controls that require pressing and holding the joystick button, because doing so opens the C2 menu
  6. C2 games are written in ES5 JavaScript
  7. The game engine includes camera movement, but only along the X axis
  8. The C2 accent color can change dynamically. Tell the Web Driver to use the accent color for the game character when creating vector content
  9. The C2 has only about 6 MB of allocatable memory. Tell the Web Driver to reuse objects with an object pool to avoid excessive memory allocation
