I tried playing through this recently and my health would keep randomly dropping to zero for no explainable reason. It seems to happen at least once in every section of the level. It would happen when I'm in combat, when I'm out of combat, it even happened in midair while I was gliding. I'm wondering if it's an emulation issue, as I'm using the 3dfx version with nglide, and I also had the same issue running it through pcem with 3d acceleration. Has anyone else had the same issue?
