[PyGame] Issue with game engine

[Donald8274]

Hello, my friends and I are trying to create a small game and I'm currently the only one who knows how to code anything at all. This is the first time I've tried to use PyGame and I rarely use Python so this isn't going to turn out well probably. Anyway, my issue lies somewhere in the NewGame() function. I'm really not sure why but it crashes once it gets into the while loop. If anyone could please take a look at it and help me solve the issue I and my team would be so grateful. I cannot upload rar files for some reason so I have put it in a dropbox.

Also, if someone could please either let me know if I'm doing a good, bad, or terrible job at coding this, please let me know and give me a few pointers. I'm not sure if this is exactly how a game engine should be.

Thank you for your time.
