Technically used the playcoin hack midrun, but the mii that was hired was not used in any way and was used just for accessing the game to climb the stairs, since the final stairs of the game don't have a boss and force an exit if you're out of Miis even if you find the stairs.

Doesn't feel very good to play for 4 hours and "lose" a run because of a developer oversight, so heck it really.
