I wouldn’t say it’s especially hard as much as it is gimped, leaving the player with no warning and essentially locking them out of inventory, etc.I know CV is a hard game and some people probably don't have the patience for it. But the game takes place on a prison island, so there's bound to be tighter than usual security. With Umbrella being in charge, you know how they are.
If they remade it, I could see it being linear with maybe one or two mediocre puzzles. Aligning crests or something. It wouldn't at all surprise me. That's one thing puzzles enthusiastics missed in the RE3 remake. Remember the music box puzzle?
