i honestly don't care what you do with the game so much as tge game gets enough recognition that other people will want to try it as well and we get a lot of people trying different things with it
in all honesty you could do almost anything with that game, you could easily go techno/trance boss theme
or you could even easier do the slower instrumental overworld melodies
it's all up to you dude, i picked the game so if you make it it's only fair if you decide how to make the song
