I unfortunately got started so late in the jam I didn't have much time to really flesh out the AI. I wanted to do more tracking, and also allow the horse to hear you, but there's always more you hope to do in a jam game. I'm just happy to have finished, and am looking forward to the next one.
I'm sorry the sound didn't work for you. I will say, my game is MUCH quieter than most of the other jam games I played, so the volume might need to be turned up for it.
Regardless, thanks for giving my game a play!
