Alchemist's Castle

Alchemist's Castle is a self-contained single-player metroidvania that launched on November 2, 2017. The store description presents the game as a complete experience with no mention of planned expansions, DLC, or ongoing content. There are no DLC listings and no developer announcements of future content at any point in the game's history. The developer's post-launch activity has consisted entirely of bug fixes and minor quality-of-life patches — addressing things like boss fight glitches, controller binding issues, and camera improvements. The most recent of these was a small bug fix on July 2, 2023. None of these patches introduced new gameplay content; they were maintenance updates to keep the existing game in good working order. There are no unreleased DLC entries, no roadmaps, and no developer statements indicating further content was ever planned beyond the base game. The game launched as a finished product and has been maintained accordingly.
