I was a tad disappointed with the soundtrack CD - I guess I hoped for more remixes of the classic tunes a la ocremix (but with less techno crap and more solid orchestrations).
The game itself is ridiculously awesome. I'm nearing 100% completion of the game with all the maps - currently trying to make sure I get 100% of the bestiary, which requires finding out what each and every enemy drops. Am down to less than five enemies, all of which are only found in the Nest (to my knowledge). Note to peeps: to get the best item drops, one would think that the witch lady is better because she gets higher luck to start out with, and double charm bracelets + her Luck spell gets her luck into the 90s.
But the fighter guy is way better with - I believe it's the Thief ring. And full luck items (like equipping the Tuxedo, etc.) and with Charlotte's Luck spell. Great for blasting gorgons and nauseum and getting 9 New York Steaks, which are great.
Then will work on getting 100% of items, many of which I'll probably have to buy from the store.
I loved the quest system and wish they had included more quests.
I also kind of wished that they had included four more distinct worlds instead of four more rehashed portrait worlds for that "final" section, but that's really a minor nitpick. I'm just glad the gameworld is so expansive.
The stylus IS used in this game, but the only thing it is used for are those three quill pens that are shown in the maps screen. There are three quills for each map, and they can be dragged and placed over the map any place you like. Very useful for marking places where you may have the entire room on the map but there is still a section you need a "travel" skill (like double jump or owl or frog or whatever) to get to.
The music is great.
I can't wait to try multiplayer coop. Might be a few months, though - don't have my DS online yet at all.
