Thank you! Background music in the game itself is a good idea. The horse collider was perhaps a bit too big for the sprite. I'll consider changing that as a hotfix!
As for Old Rock -- good on you for giving it your best! Though the young man should question if it is worth the effort, or even possible at all, to complete the journey. After giving the game a few attempts, maybe stop for a bit to contemplate if you should mount the horse again! It might be smarter to just give up and try to go home ;)
