Hey Colin, thanks for checking out the game! Sorry to hear about the issues. We tested the build on four computers and didn't run into any issues with the bus falling off of the track, so I'm afraid I can't offer much help there.
For the keyboard controls, my priority number 1 was to make it so that you didn't have to move your hand, and my priority number 2 was to make it so that you were aware of how to reset / return to menu in the event something goes wrong. Statistically speaking, people never read up on the controls 😅 so in the case where I didn't have enough time to make a proper pause menu, I opted for people possibly accidentally resetting the game instead of not knowing how to pause, getting frustrated, and Alt+F4ing as the lesser of two evils. Whether you agree with that choice or not is completely fine, but either way thanks again for playing! 🙂
