Nice game, you used Pygame, didn't ya?
One tip, you may be knowing that but whenever you are making an exe file of Python (using cx_Freeze at least), you don't need to pack other scripts you used and __pycache__ directory, cx_Freeze automatically packs the scripts somehow in the package and for __pycache__, it's just a cache directory for Python, so you don't need that as well!! :)
Anyways, how did you enable FPS meter on the Title Bar of the game?
