Evaluation
Terrorhedron Tower Defense launched on July 24, 2014 as a finished product. The developer — a solo developer named Dan Walters — posted a handful of updates in early 2015, including bug fixes, a Steam lobby feature, and Steam trading card support. The last recorded communication from the developer was on May 10, 2015. No updates of any kind have been posted since that date, no future content was ever announced, and there are no DLC or expansion listings of any kind. The store description makes no mention of planned additions. The game appears to have launched as a complete, standalone product and received only minor maintenance and quality-of-life additions in the months following release before going quiet entirely.
Evidence
Developer added Steam trading cards — the last known developer communication of any kind.
