I knew Holy Wow from their Icarus Proudbottom games, and I'm glad to see them survive the death of Flash. As a wacky comedy game, Trombone Champ fares alright - the central joke never gets old, but the rest of it often gets dated or juvenile - but what surprised me most was that it wasn't just a wacky comedy game. It's actually a really fun rhythm game underneath it all, and I can't wait to see what kinds of levels serious players will end up modding in.
