Perfect score from me. I think the most underrated thing you did was improve everything the OG did poorly. Something as simple as "Frontal Arced Bomb" made that part of the UI 10000 times easier to understand. Not to mention that the enemies don't blend into the background since you actually designed good characters.
The only thing I even had a small issue with was the FPS. I loved switching into this perspective, but there were times when this perspective became really hard to play. I'm certain that for the character controller to be compatible with both top down and FP, you had to think way outside the box, and I think you got it working well, just not quite 100%. That's such a small nitpick though, I can't emphasize enough how amazing this remake is.
