Summer Courage Challenge: The Seven Mysteries of CAVEDUCK Academy

This is the first time I've tried using a large amount of Lorebook content. I'm quite satisfied with this work.
I've wanted to try making a simulator with a Cthulhu TRPG style for a long time, so I took this opportunity with the submission event to create one.
Due to the extensive use of Lorebook, in order to play normally, I recommend using models above gemini 2.5 pro. gemini 3 flash is generally playable as well. Additionally, it is recommended to enable "Replies containing multiple images" in the model settings.
Also, during testing, I found that Lorebook seems to only allow up to 10 entries to be active simultaneously. While it's usually fine for normal gameplay, I'm not sure when issues might arise, so it's best to try not to stray too far from the main storyline.
