I'm sorry, the game is just that incomplete. We wanted to have some sort of end at a fixed point, and then an endless mode where the levels just keep going until you run out (which would have needed a lot more levels to be interesting). As for throwing the torch, the idea was that certain levels would force you to drop it temporarily (to go through a water section, for example), or allow you to choose between a slow path where you keep the torch and a fast path where you don't, that kind of thing, which might give birth to strategies. But again, we didn't really get time to do any of that.
