if p1 and p2 both want to play as daisy:
p1 hovers over daisy, presses A to confirm, presses B to cancel, then moves the cursor
p2 hovers over daisy, presses A to confirm, then presses B to cancel
then you press B to go back a menu, A to go forward a menu, and both your cursors are over daisy so you can both just press A
@noiob they might accidentally make the game playable locally for people who care about stats :P
