I'm glad that one of the tracks reminded you of Fire Emblem! I love that series and its music has inspired me to pick up composing in the first place, so your comment made my day!
I agree with the boss battle theme lacking a bit momentum, and chord movement was a thing I was being careful with the other tracks but ended up not revisiting for the boss theme. It would help improve the track, along with adding more rhythm to it.
Ok so Wi-Fi Settings is a bit of a joke track, I was just feeling nostalgic for the times where some UI menus had its track of its own. Let's just say that this is a uuuh very late SNES-era game with some internet features.
Thank you so much for your comprehensive feedback!
