Quite a fun game, the level design for the most part is great, aside from the sewer. I can imagine all the verticality and such would be mind blowing in 1995, though the way you sort of slide when sprinting and jumping can also be a bit of a hindrance. Hardest level without spoiling is the one with all the stupid mines, only difficult and annoying thing in the entire game. Quickly setup The Dark Engine to save you money on the remaster for basically the same experience.
