Raylib 32x32 competition template
/**********************************************************************************************
*
* raylib 32x32 game/demo competition
*
* Competition consist in developing a videogame in a 32x32 pixels screen size.
*
* RULES:
*
* 1) Use only raylib (and included libraries), no external libraries allowed
* 2) The submission should consist of just one source file
* 3) Render your game/demo to a 32x32 pixels render texture,
* show what you could do with a 32x32 RGB LED matrix!
* 4) No external resources, you CAN only create them programmatically,
* 5) Game/demo can be 2D or 3D, choose wisely
* 5) Shaders (if used) should be included in the source as string (char *)
* and loaded with LoadShaderCode()
* 6) Code must compile and execute in PLATFORM_DESKTOP (Windows, Linux, macOS)
*
