+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)
