As we would say in my language: "Una carta de amor a la musica, 20/10 y GOD". Which is to say it's an excellent game and I can't wait for some new content. Hope you get well soon and blessings.
Maybe you saw already but if you sign up to be a playtester: here you can try the playtest version levels (~20 so far) after I send out new download keys.
I think I'll probably send out the next batch of keys in a couple of months or so.
