Some calculations: I'm at a quest which takes 5 energy for 1 attack. You can buy 5 energy for 1 platinum. So 1 click = 1 platinum and 15 platinum = 25 kreds = $2.50 so 15 clicks = $2.50 so 1 click = $0.16. WTF?
100% progress – Note: This will be nearly impossible until you've played a bit and developed a good amount of starting cash. Plan your upgrades wisely!
