Now... Wow. You always hope when you're competing in a Jam that you can really make a complete package, but usually you can see where things got cut, or the whole thing becomes something of a proof of concept. But this really did feel like a complete package.
I think I died on melody 6 about five or six times before I finished it, but it really felt like a proper 'boss' fight song, and is stuck in my head now. Lots of fun, and super impressive it was done in 72 hours. Really glad I played it.
