The Jjaro have fallen. Perhaps you should as well. (Of course, to fall, you must first ascend...).
I should know this better than anyone, but things have changed so much I can't remember what version was how; isn't Giants exactly the same as all the previous dream levels? I don't recall making it any different, other than monsters (if there are any). Unless I reversed the direction of play, but I don't think I did that until Eternal X. Oh wait... in Mk V, do the various dream levels get progressively longer? And now you're at the top of the mountain and don't know where to go? If so, see my first advice above. If not, where are you stuck in the level?
