Hey! That's a pretty good Halloween deduction game! I could see a bigger version of it!
What stands out the most is the writing. In a game where the main mechanic is reading it's pretty important :) Luckily it was fun to read and not "skip dialogue"! The gameplay was fun. Implementing two types of gameplay for a 4 day jam is a bit of a gamble, but you made it work.
The presentation was good. I liked the assets, although I guess the cup icon looked more like beer glass than a coffee cup to me. The music fit the atmosphere pretty fine.
As for the theme- I think you had a really interesting take! Although I really feel for the barista. Working full day AND THEN THE NIGHT SHIFT? Hardcore!
