Meh. Considering the budget, it's impressive how long this game is, but the repeating locations, shit ton of pointless backtracking, and lack of any memorable level design makes it questionable for such game to even be finished. The story, for how important of a task it tires to accomplish, doesn't deliver any hard hitting moments or significant revelations, and the game is simply not worth the 8 hour playtime it asks.
Strangely enough, Castlevania 64 ended up being a far better game.
