This is an excellent game. I can tell you've put a lot of heart and soul into it. I loved all the flavour text from the NPCs. The game itself was fun and just challenging enough for me, it took me a few tries to nail it as I've never been great at rhythm or bullet hell games.
I think the only criticism would be that the rhythm moves didn't seem to line up perfectly with the beat of the music, but it's such a minor issue I almost didn't mention it.
Overall, extremely polished and fun entry, I think this one will do really well.
