Great job!
It shows a LOT of improvement from the first version, which I went and downloaded a while back.
I remember the tiptoe-ing on air glitch, and some super jump glitch I'm not sure how I activated, but neither seemed present in this version.
The castle is MUCH bigger. It was nice to see the first bits of the castle still like in the original, but it feels huge. I'm 99% positive I missed a lot of stuff in the game.
The aspect of Stealth and Health, very well thought out. I kept at 100% health for a good part of the game, but my Stealth fluctuated a lot. Once I figured out a few moves that gave me Stealth back, I tried to use them as much I could.
There's a few things that I wonder about, though. If you come from behind an enemy (while holding a staff) and smack them into the camera, shouldn't that give Stealth (that is, assuming that the enemy isn't alerted/locked onto you)?
Also, my hide seemed to not work at some times, but I was probably too close to a pillar. XD
All in all, a great improvement, and a hell of a good job.
