Cubicolor

Cubicolor is a self-contained minimalist puzzle game that launched on March 18, 2016 with a fixed set of 50 levels. The store description describes the game as a complete package with no mention of additional content, expansions, or post-launch plans. The only post-launch developer communication was a May 7, 2018 update that rebuilt the game from the ground up and added controller support. In that post, the developer mentioned plans for "a series of upcoming updates" to improve quality of life and fix long-standing issues — but this language refers to maintenance and polish work, not new content. Crucially, the game's store description still describes exactly 50 levels with no mention of added content, and no such quality-of-life updates or new levels have been announced or listed. Since May 7, 2018 — over eight years ago — there has been no further developer communication of any kind. The 2018 promise of follow-up updates was never fulfilled with any announcements, and the game's content description has remained unchanged. No DLC has ever been listed. The game was launched as a finished puzzle experience and remains one today.
