one little suggestion: make the costume you get for bridge a boy and the one from block drop a girl. anyone who finished either of these games change the costumes into their new versions. why? Well the rarity of the costume from block drop will get taken away, making it less cool for anyone who got it as sort of a “collectors item” from a limited event.
Hive plans on adding new costumes for max levels in the near future. Not sure if they will be a boy and girl.
