Hi Parsley, thank you so much for playing my game! In the room with the first glass of wine there are two doors. The one on the left will take you to the exit once you have the key. You can find the key by going through the door on the right hand side.
Keep going through the doors on the right hand side and you should find a key :)
Let me know if that works for you. :D
There is so much more to explore once you leave that place, don't worry. :)
I'm glad you like it so far!
