Quoted from KingofGames:
Well your first two ideas dont work.
The point of the game is not to play the same adventure twice. So for 99% of the games it would force you to make a choice with zero results.
The multiball sounds interesting
True, hopefully there are enough adventures that there wouldn't be repeats - even for a long game. Maybe a successful completed mode (instead of timing out or draining), could give a cursed item that could just be used on any future adventure instead of a hypothetical repeat.
Fingers crossed on some form of dimension hopping multiball though.
