Was thinking ... when you have completed all the puzzles and quests, rather than just wandering around whacking bushes in whichever area to raise your level, a NPC offers you a chance to reset the all the rooms and quests back to when you first started playing. You would keep your current level, items, etc, and wouldn't win the same item again when completing a puzzle/quest. And if possible, make the puzzle/quest items harder to find second time around.

If any of this can easily be coded into the game, even just for resetting a single room at a time, it would give us something to work towards rather than just whacking bushes for the sake of whacking bushes.
