a math problem for the game, how many tier 1 item do you need for a tier n item? for example, tier 2 need 3 and tier 3 need 8... btw i wish someone could make a non pay version of this, the rule is fun but the pay part is dumb
guess what? for the bolt badge, i explore the FULL map, and i found ZERO bolt, and i have to grind 4 more stupid map again to get another chance! bad badge
