I could see that being sweet. I really want a smoother tenchu experience next time around. I worry that using Creed would just result in Assassins Creed: Japan. <=== not a bad thing, just not Tenchu.
The repetitiveness, yeah, that could be addressed. More mission objectives would be fun. Aklso, the rope should be toned down a bit, maybe you actually need to SWING on it, like in spider - man 2. I mean, it's NOT Batman's rope from the animated series!
