Hello goodluckNito! Thanks for checking out our latest game, and happy to hear you enjoyed your first shift at Happy's Humble Burger Barn!
1. The purple cassette should be working in the boombox. (It features the theme song from our last game, "Entity.") Did you use the left or right click when you tried to put it in the boombox?
2. It is not possible to take orders at the drive-through, although this was the original mechanic that sparked the game! (Or so that's what I think one of our programmers said.)
3. My reaction to you escaping the simulation early: 
4. That was taken out of the game. It was gonna be hanging up in the employee break room but we took it out for any kids who might play the game.
