I am sorry but the game shuts off immediately when I try to run it even before I can see the game screen :/
Did you do a space between pgzrun and the file?
(btw I played your game and its quite fun, but im not that good so only got to lvl 4)
I also had the issue at one time ill try to remember how to fix it and get back to you asap
What was your process of doing it?
I downloaded and extracted the zip file, then tried to run the .py executable. And thanks for playing our game! If you are stuck at a level you can check out walkthroughs at the description to get some ideas.
