 # Simple OpenGL FPS (C + FreeGLUT)
 
 A tiny first-person demo using legacy OpenGL (compat) and FreeGLUT:
+
 - Move with WASD, hold Tab or Q to sprint
 - Aim with mouse (captured by default). Press M to toggle capture
 - Shoot with Left Mouse or Space. Hit the red cube to score; it respawns
@@ -24,9 +25,11 @@ make -C C/fps run
 ```
 
 If your distro uses different package names, install the equivalents of:
+
 - libgl1, libglu1, freeglut (dev headers)
 
 ## Notes
+
 - This uses old-school fixed-function OpenGL for simplicity and broad compatibility.
 - Mouse is confined via glutWarpPointer; press M if you need to release it.
 - SDL2 is used only for simple procedurally generated sound effects (shoot, hit, game over).

 - ESC clears selection.
 - Press `m` to cycle to a stored mistake position and practice the best move there.
 - If you play Black, the board flips so Black is at the bottom.
