Neat game, impressive that someone else used pygame-- I also used pygame so I'm super curious about how you exported your game.
I thought the timer blocks added a neat twist!
I exported it into an .exe file by following these instructions: https://www.geeksforgeeks.org/convert-python-script-to-exe-file/
But I think you still need the .exe file in the same folder as the original .py file for it to work.
