The game has one decent shock moment (other than the actual final boss) down in the catacombs of the first level; red fish men a la Creature from the Black Lagoon jump out of the water in between spaces where the player jumps.
The remake gives the original Level 5 (now 7) an especially gruesome facelift, decorating the laboratory areas with skinned and dismembered human corpses, exhumed coffins with dressed bodies in repose, and a library populated by tiny homunculi that burst from jars and attack you. Once you leave here, you come upon an art gallery with a "painting" that is essentially an enormous, flypaper-like trap filled with victims who struggle in agony (the ones whose faces are exposed, anyway; many more are clearly dead from suffocation). And then there's the music.
