I suggest it have a overral, the amount of currency you gain is too little to buy the item needed for the quirky upgrade( you only get 25 per week) and the amount of coin you gain from boss is barely 200, also fight against them multiple time isnt really a good idea, should have only 2 fights per week instead multiple fights, it should also drop the item require for the quirky upgrade during those fights. As it is now you fight multiple times barely getting the coins and the fight get hard and harder
