Chrono Harem: Artifact of Syr is an adult dating sim by Mynomyni, built in Ren'Py with animated 3D visuals. You play a male protagonist who moves between two linked timelines: the present and a strange sci-fi future. The game mixes relationship choices, sandbox-style exploration, and secret uncovering in a fantasy setting as your decisions shape the outcome.
The current release is v0.2.4.3A, dated August 22, 2026, and development is ongoing. It runs on Windows, Mac, Linux, and Android, in English and Spanish, with no censorship. The latest update introduced hints that were missing for Maggy and the Captain, and fixed a problem with Bunnygirl's ready meals in the inventory. Previous builds in the Bunnygirl series mention adjustments to saving, email, and holo systems, along with new interactions and a cheat option.
