Since there's some people that can't buy crowns. But don't want to get it for free/handed to them. Then why not crown achievements? Something like, "kill 50 brains with energy cannon" Reward: 10 crowns. It aint much, but at least its a way to earn some or for difficult ones like "Mine 4 different color natural crystals" Reward: 50 crowns. Is this idea good or bad? What's your idea or add on to this? Please. Constructive critism. Thank you.
