I like the audio tracks a lot. The loops are polished, expressive, and wear well, with good levels of tension, so they should work as game play gets tenser or relaxes. Getting game play to have dynamic arcs can be a challenge though. There’s always a danger of: “oh there’s another monster, kill it, walk walk walk, oh there is another monster, kill it…” which can get a bit flat.
I don’t know if your audio system is set up to do this, but (small point) instead of looping a flaming torch sample (the sample you have sounds like a good one), can you play a continuous stream of slices from the torch sample? I’m thinking slightly overlapping 1/4 or 1/5 second slices, selected randomly from the sample. As long as the player is moving around, the torch audio is long enough that you don’t hear the loop. But if a person stops by a torch, it can become apparent. Something similar to the treatment of the brook sound here might be a small but nice touch. Am happy to share the algo, but I don’t know your audio system. Can you output a continuous PCM data stream as audio?
