TransPlan

TransPlan launched on June 8, 2015 as a finished puzzle game. In the weeks following launch, the developer shipped a small number of updates: a feature patch on June 12, 2015 adding a new achievement and minor UI improvements, a bug fix on June 25, 2015, and a content update on July 9, 2015 adding ten new "Master II" levels. That July 9, 2015 update represents the last developer communication on record and the final content shipped for the game. There have been no announcements, patches, or posts from the developer since that date — over a decade of silence. The store description describes a fixed set of hand-drawn puzzles with no mention of ongoing updates, seasons, or future content. The game launched as a self-contained puzzle experience and has been complete since mid-2015.
