One of the harder bosses, Galamoth (the very big gold guy) was giving me trouble until I remembered to get the Beryl Circlet first. It makes electric attacks heal you, changing the battle from an exercise in futility to a joke (still took about a billion hits, though).
I love the "reunion" battle where you fight fake versions of Sypha, Grant, and Trevor Belmont from Castlevania 3. That was a great touch. I also like how your save game icon on the memory card changes frequently. The most recent one I saw seemed to resemble Konami Man, which was an odd but fun reference.
So far all I've been doing here is lavishing praise, so I might as well give some attention to the things I'm not crazy about in SOTN:
- I wish there was a way to organize your inventory. The fact that your weapons, shields, and consumable items are all jumbled together in one huge list seems counterintuitive to me.
- There are some cheap deaths, such as in the dark room you have to navigate in bat form with your echo power. If you mess up and touch a spike, there's a decent chance you'll end up in a damage stun loop you can't recover from and end up dying.
- As well-designed as the inverted castle reveal is, this game is packed with so much content and so many secrets that a player would likely never figure out without outside help. One of my favorite swords, the Jewel Sword, is hidden in a room you can access by going through that tunnel near the beginning of the game you have to smash open both ends of, but you have to go through it in bat, wolf, and human form. There is absolutely no way to guess this and I wish the designers would have found a clever way to give you a hint. In the Colosseum, for instance, there's an area where you see small engravings of stick figures on a wall. Why not use these background details to give you hints about secret stuff you can do? The shield rod has a unique special move for every shield you can equip it with, executed by pressing square and circle at the same time. This is a great feature that adds visual splendor, gameplay variety and practical effects, but as far as I know the game does nothing to let you know this is even a feature.
- The duplicator is WAY too expensive. I understand that it's kind of game-breaking and it shouldn't be easily obtained, but unless you cheat and exploit a glitch you're going to have to spend at least a good couple of hours grinding until you can buy it, and that's if you farm the $1000 candle in the Colosseum while using your Shield Rod/Alucard Shield special ability.
- Once you find the Alucard sword, you're still going to discover a ton of new weapons but there will be very little reason to ever equip them. Seems like a shame.
