yeah, I was so addicted I finish it in 3 days
The game rocks. I went back to find all the artifacts I missed.. like 18 and there were a few that were really hard t get... specifically on the emerors tomb level with the floating bridges. OMG I had to go back to that other three whip swing place when entering the chinese fortres just to practice.
Speaking of the entrance to the chinese fortress, I found an AWESOMe trick where you can bypas a lot of the first part of that level. You jump down from the first platform which is above and left of the walkway where you meet the first mob... jump straight towards the wooden post, whip at the right time and you swing up and land next to the area where the secret is.
X never marks the spot.
