I have just started slaying my fifth Golem and, although the experience appears to have a far more appealing end-point than the Balloon Frenzy, I feel that an improvement would be to be able to slay any of the Golem's three hearts as and when the user wants. Presently, I am converting marble to marbles (72k marble) and all of this must be cast on the Golem before I can start on the rope or water hearts. Whilst I am mining / trading more marble, I would be unable to continue my slaying with stocked rope / water. If I could choose which heart to attack, I could slay the Golems much more swiftly with far less waiting time.
