Trombone Champ

Trombone Champ launched on September 15, 2022 and has been actively developed ever since. The base game has grown substantially through free post-launch additions, more than tripling its original tracklist to over 60 songs. Three paid song pack DLCs (Undertale + Deltarune, Pizza Tower, and Celeste) launched on December 18, 2025, followed by a free content expansion to the Undertale + Deltarune pack on March 19, 2026, which added 7 tracks from the Deltarune Chapters 3+4 soundtrack. The developer's most recent communication was on March 19, 2026 — roughly 6.5 months before today's date of October 8, 2026. In that post, Holy Wow Studios outlined several ongoing priorities: bringing DLC to the Nintendo Switch version, exploring a Switch 2 engine upgrade, improving controller support on PC, and working on prototypes for new games alongside continued Trombone Champ support. The broader timeline shows a developer that has consistently delivered: 5 major content updates, 11 feature patches, and 27 bug fixes across the game's lifetime. The cadence between major content drops has generally ranged from roughly 3 to 9 months. The March 2026 post is now approaching the outer edge of that window, but it explicitly stated there is still "work to do" without indicating any conclusion of development. The developer noted in June 2025 that they were "probably done in terms of significant updates" after completing their roadmap — but this was superseded by the December 2025 DLC launch and the March 2026 content expansion, both of which demonstrated continued meaningful content delivery. The December 2025 post also floated a potential Celeste B-sides pack "at some point in the near future," which has not yet materialized or been ruled out. No statement from the developer has announced the conclusion of content development for the game. The silence since March 19, 2026 is approaching the threshold of concern but does not yet clearly exceed it given the established pattern and the explicit "work to do" framing in that last post.
