We literally opened a case and started poking around in like 30 seconds. No PDFs. No 47-page host guide. Bless whoever decided to kill the printer drama.
The board got messy (in a good way). Timelines, suspect stuff, little clue cards popping open—chef's kiss. My friend said, 'I feel like the over-caffeinated detective in a show.' Accurate.
Some panels are a bit 'coming soon' but chasing the threads was legit fun. We argued about a receipt for 15 straight minutes. Needed snacks. Worth it.
Invited people over. Opened a case after dessert. Everyone instantly suspicious of literally everyone. I barely 'hosted'. 10/10 lazy GM experience.
Already solved it, came back as the 'ghost narrator' guiding new players. Watching them chase the wrong lead? Pure entertainment.
We all huddled around my monitor like it was a forbidden artifact. Digital layout keeps the chaos contained vs paper piles. My table is thankful.
Beta being totally free feels kind of outrageous. I'm mentally ready to throw money at premium stuff when it lands ngl.
Screen sharing works but I want everyone clicking around in real time like gremlins. Devs, I believe in you. Make the chaos scalable.
Case said '1–2 hours'. We took 3 because we overthought everything and someone made a suspect spreadsheet. Zero regrets though.
Had a clue load kinda slow once; we mocked it and moved on. Otherwise buttery. Dark mode supremacy.

In the secluded, fog-choked town of Black Creek, Maine, some secrets are woven into the very wood and stone. On October 28th, Eleanor Vance, Age 24, disappeared. Her last location was 412 Hemlock Lane—a house heavy with its own history—where her grandmother, Edith Vance, maintained that Eleanor simply left. The front door was found unlocked. Her keys and wallet were on the counter. The only item missing: Eleanor's private journal. Days later, it was found near the old Black Creek Bridge. Its pages were not the record of a sane mind, but a chilling testament to a descent into shared madness: > ...the calls come after three. He never speaks my name. Only hers. > The local report cites "severe isolation and self-induced psychosis," pointing to Ellie's obsession with the single, whispered word in her diary: Cora. Yet, in Black Creek, a name is never just a name. It is a promise. It is a warning. Eleanor Vance's body was never recovered. The file is closed. But if you look closely at the faded photographs and the scribbled entries, you have to ask: Did Eleanor wander off? Or did she answer the call of her shadow's name?
A high-stakes cold case. Realistic evidence. Your call on every lead.
