Python 3.6 to executable

[snippsat]

It still doesn't work, just closes like before.

What do you mean do the .exe start and it close after finish?
If that's the case as mention before in last line.

input('--- Press <Enter> to exit ---')

Star cmd first(not double_click on .exe)then navigate to .exe and start it.
Doing it like this then cmd window stay open and you can see if there is a error message.

Your way over doesn't seem to work as well, but I'm sure I'm doing something wrong.

I think you most do something that i don't do,every step i do is in my post and game.py is just copy and paste of your code.
It generate for me a working game.exe.
