Kasedo Games has done a phenomenal job at supporting The Metronomicon post-release, releasing three DLC packs since the game's release on September 29:
Chiptune Challenge Pack 1,
Chiptune Challenge Pack 2 and Indie Game Challenge Pack 1.
The most valuable of these items arguably came in the first DLC,
Chiptune Challenge Pack 1.
During my time with the game I was also given the opportunity to try two of the available DLC packs, with
the Chiptune Challenge Pack 1 and the Indie Game Challenge Pack 1.
