For those trying to run this..., you need to have Python installed. I also had to install pygame first: py -m pip install -U pygame --user
Then, I was able to run py dodgingLazers.py from the directory with all three scripts.
As for the game, the most frustrating part was that the predictions didn't match where the lasers actually shot, so getting hit was completely unpredictable. The controls switching was definitely out of control! I would recommend some better way of communicating what the new mappings are.
