hey ho, sorry for the crash. I'm going to try to see if I can fix this, but this was just a student project done in like two weeks years ago running on a now very outdated version of Unity. If I can reproduce and fix the problem, I'll let you know here, but I can't promise anything. I'm sorry :(
EDIT:
Just did a quick replay and it's not a bug, that's actually the end of the current game. As I said, this was just a quick thing we did during a class teaching how to pitch a game, but we were never able to fully develop it after. Sorry again ^^
