The verdict

A short asymmetric co-op puzzler played over voice chat, with a charming noir look but jank, bugs and AI-art suspicions. Skip it if you want length, depth or a solo game.

Great for

Couples or friends wanting a cheap, short evening of talk-it-out puzzles, ideally on sale

Main risk

Only about 2 hours of content, needs two copies, and has bugs, no saves and unclear interactions

What players love
