I am intrigued by the description for the game. Unfortunately, I could not find a way to progress the story - I did get a croissant but not where to put it. Whatever I tried to make the coffee machine work failed.
Please advise
Definitely realizing this game needed more tutorializing, sorry!
For the coffee machine, pickup one of the cups beneath it and then click the machine (if it makes a sound, it worked).
To serve items, once you have an order (by clicking the register) place items on the tall counter with left click/E. It should be lit up. Serve by clicking the register again.
EDIT: Add creamer to coffee by holding creamer and clicking on a coffee once it's been placed on the counter.
