very nicely arranged — the tension of the piece is already established with the introductory strings, and the slow introduction of the horns as we approach the climax of the piece is a nice touch. nice work!
the transition at 1:12 did surprise me a bit, i was expecting something to transition into it; but i also do like the spontaneous change in volume dynamics for this section! it's rather fitting given the videogame-specific context you envisioned. love the reiteration of the almost rhythmic melodies from the beginning but now in the piano for the end! :D
