First, I hated that the battle music started whenever an enemy detected you. To me, that's the wrong cue. It telegraphs to the player that they are in a battle situation and it usually does it well before the player has even figured out they are under attack. I don't need an early warning system like this, it takes away some of the fun of being ambushed or surprised.
Rather, I think the battle music should cue when you are actually attacked. That way the attack comes out of nowhere and you can be caught completely off guard. Every now and then I am still surprised by an attacker, but I do wish it happened more often.
Second, chasers follow you too long. I'm not complaining about humans or animals like wolves that can run quickly, but mudcrabs here. Mudcrabs used to follow my character FOREVER. There was no hope of them catching up to me, and I had to listen that that annoying battle music the whole time. I would rather listen to the lovely woodsy music for two reasons:
I never got attacked by the mudcrab, so the battle music shouldn't be playing at all, AND, it certainly shouldn't keep playing for half an hour after I run off.
So that's my comment. Please let the battle music cue to actual combat so that we don't get so much of a telepathic heads-up about enemies nearby, and please cut the chase shorter when the enemy has no reasonable chance to catch you.
