Really cool idea. I saw your warning about the space bar and then immediately forgot (even with it right there on my screen) and went to write notes in the link notes and had to start over, hahaha.
I wasn't sure whether the dialogues that had no text in them were intentional or not, but I hit some of them more than once by mistake since I couldn't remember which things were said (should've been writing notes on paper for myself since the game didn't "mark them as read" which is totally fine for game jam scope :D ). I think maybe I needed to link the topics on the main bulletin board in order to get more text, but maybe that wasn't it. It was occasionally difficult to keep straight what someone was talking about since they'd launch into talking about someone (who wasn't necessarily the one you asked about).
I thought the game atmosphere hung together well, and I enjoy mysteries a lot, so thanks for the experience! ^_^ Cheers.
