I played it for awhile today and it's awesome. Saying that this is Phantom Hourglass 2.0 would be like calling Majora's Mask "Ocarina of Time 2.0". This game is not just an improved Phantom Hourglass.
To me it is.
I mean, it's not like that is all the game is, but to me it was a lot of the issues I had with PH being washed away, like it was an improved version of it. And I mean that in the gameplay, controls, story, etc.
That is what sequels do and it should be expected. Sonic 2, Halo 2, Gears of War 2, Assassin's Creed 2, Megaman 2, etc. Calling it 2.0 implies that this game is somehow not its own game and is simply an updated version instead of the true sequel as well as giving you a cheap shot at the previous game by saying it wasn't "complete."
Anyway, back to the game.
The tower in ST is very different from PH. Each level is essentially a full dungeon complete with a boss key and miniboss.
I'm in the dark floor and I love drawing my own map as I go. It also does seem harder than PH so far.
Halbred, bite your tongue. Blowing into the mic is an amazing way to play the flute.
