Good idea. It was a bit confusing at the beginning but after that it was a fun concept.
If you are thinking on polish the game further after the jam here are some suggestions:
- Maybe place the coffee in the middle, so you could set it up, go do something else and then drink it to the way to the next place.
- There could be some slight indicator of what went wrong, is a bit frustrating not be sure what was the mistake.
- Skip initial dialogue.
- Time should stop during reading signs. maybe display timer when using the computers.
