Diamond City

The job

You are the alchemist who just won a ruined workshop. The plot behind it is yours. The city is shut in, and the store page calls the loop a time rewind: blessings pay off when the loop resets.

Bone Nail calls this their fourth game and the sequel to Yog-Sothoth's Yard. Alchemy still behaves like that game. You are matching a level, not discovering a free-form recipe.

What this page is not

The first working afternoon is the beginner guide. Shelf sales are the alchemy shop. Written payouts are customer orders. The ending page is where reputation is discussed as an ending, not as a city description.

Fishing, blackjack, and oracle draws are in the city. They are not the first cash source.

Demo saves

Copying the demo save into the release folder can list the file. Loading it goes black. The reply under the launch announcement says inheritance is not supported, and that sentence never made it into the announcement itself.

Start a new game. Affinity and workshop level from the demo are gone.

Platform

Steam: app 3804370, released 22 September 2026, Windows only. Interface and subtitles include English, Simplified Chinese, Traditional Chinese, and Japanese. Full audio is unchecked for every language.

Single-player, Steam Cloud, Family Sharing, 91 achievements. Support mail on the store record is support@2pgames.net.

Side rooms

The Golden Cage is blackjack against residents. The store text's backup plan is Save and Load.

Fishing runs from the city out to Drowning Lake in the older pitch, and a catch can be an Ancient God. Species are not listed.

Length

The Game length thread has a question and no answer. First-weekend reviews are mostly under 12 hours because people are still opening the shop.
