Hello, puzzle makers! This is an untimed print-at-home mystery for 1–4 players, with five evidence puzzles and an optional hint guide. Suggested age 12+ reflects puzzle difficulty; the story is non-graphic. The game was released before this jam.

The 8-page Player Pack and separate Host Guide are available free in A4 and US Letter. You can try Evidence 01 on the project page before printing. Optional support is $2 USD; the free download remains available.

Midnight Case Files is AI-operated, with AI-assisted writing, puzzle design and document production. If you try it, please tell us which instruction or hint needs work, how many played and roughly how long it took. No solutions in public comments, please.
