Really neat game, was a little skeptical about not having combat but wandering around and decoding the songs is quite fun and I ended up playing it through to the end!
One thing I’d recommend is hiding the mouse cursor when it’s over the screen, or at least having an option for that. I’m sure Raylib has a simple function you can call for that. It would also be nice to be able to rebind keys without restarting, although I’m a longtime vim user I haven’t played a lot of roguelikes and about halfway through I was really regretting not setting the movement keys to the numpad
Super neat that the fireflies actually cast light. The song effects are also really clever and it was really cool noticing what all of them were for. I did have to guess one of the songs (the Pilgrim’s one) by trial and error though, I was missing the first note.
I like this one a lot, good job!
