Nice job on tying everything together, and bringing those themes from the first two tracks back around for the finale. Every track feels good and serves it's intended purpose well. No hate here, but I have to admit - my first thoughts on the battle theme was "tell me you love Final Fantasy VII without telling me you love Final Fantasy VII" lmao.
I feel for your struggles on Eryndor's Madness, I've definitely been there (in a battle to the death with a piece of music) and I'm glad you came out on top! It turned out to be a jam-packed little ride through hell and back. Nice work on your story and soundtrack all around!
