It's very clear this game defined the 3D platforming gaming industry back when it released. For the time of it's release there are lots of amazing feats that were handled here when it debuted. That said I can't help but feel like the levels after you reach the clock tower upper area of the castle just aren't as good as the lower floor levels. And there are some parts of levels that just feel sluggish to go through. With that said this is a nice comfy game to go through.
