- Exact times and estimates stay distinct on the timeline, while saved work remains on the player’s device.
Field notes
The case file includes witness statements, photographs, medical examinations, and hotel records. Players make their own Cards rather than choosing from suggested deductions, and the timeline keeps exact times separate from estimates. The site says saved work stays on the device and does not sync between devices; it also lists an offline copy. The 3D hotel requires WebGL, with a laptop or desktop recommended.
