I've got a suggestion for the Guildhalls. You should expand them, and put a boss fight mode in. You get to fight any of the bosses you've already killed. If you win, you don't get any tokens, you must spend 10 energy to get to the fight, and you get to keep all the crowns and heat you acquire throughout the fight. This is just a suggestion, would be appreciated if it was put in. =)
Kinda like a practice? +1
