Evaluation
Castle of Shikigami is a PC port of a classic 2003 arcade shoot-'em-up, released on Steam on June 15, 2017. Following launch, the developer shipped several patches through October 2017, including a major free update on October 5, 2017 that added Practice Mode and a slowdown option. Both DLC items — the Soundtrack (June 16, 2017) and the "Evolution" content pack (October 26, 2017) — have been released, with no unreleased DLC remaining on the store. The most recent developer communication tied to this specific game's content was in December 2021, and even that post was primarily an announcement about other titles (Castle of Shikigami 2 and Crimzon Clover World EXplosion), with Castle of Shikigami 1 only referenced in the context of a series bundle. There have been no announcements of additional content, roadmaps, or further updates for this title. The game launched as a complete, finite product — a faithful port of a finished arcade game — and all planned content has shipped.
