I'm glad you enjoyed our game, especially the attack mechanic! We are very proud of that part. The map design isn't the best and that was something we hoped to come back to and improve if we had the time, but sadly we didn't. The music glitch was very disappointing for us because it only appeared when we uploaded the game and we couldn't find the cause before the jam ended. It happens sometimes and sometimes it stays and other times it is fixed when you reach a checkpoint. Again, very disappointing. To answer your question, yes the game is infinitely long. You will deliver one king, then start the journey to deliver the second, and so on.
