A classic of the 2.5D platformer genre that lived and (mostly) died on the original Playstation. There's both a save option and a password system, a bunch of secrets to find, and plenty of different stages to play. The controls can get wonky if the perspective quickly changes and a lot of the weapons are situational or generally useless but it's a personally important game to me so I'm willing to overlook a few flaws here and there.
