I disagree about the items.
I thought the game was very innovative with items.
Ball and chain: THis was new item. To have a power weapon with physical attack. The ball and Chain was slow, but definitely effective when the hit was made. I thouht it was innovative to swing it around your head, aim and throw. It was used for several different things in the game play: breaking ice blocks, making platforms swing/move, and moving blocks around.
Spinner: Another new and very innovative item. Used more as a tool than a weapon it allowed a whole other type of 'puzzle game' Having to jump back and forth from rail to rail to get to a certain spot or make it past danger this item opened a new door for gameplay. It did function as a weapon in some instances, having enough speed allowed you to level some enimeies at least as a first attack. As well as providing a very different fighting style for a boss match. Though this item reminded me of bayblade, i really enjoyed the innovation.
Double clawshot: now, here is an example of an old item that got a much needed update, but one that performed well. The clawshot was much more explanatory as to how it worked than the hookshot/longshot but served an extremely similar function. The addition of the DOUBLE clawshot seemed unnecessary at first and redundent, but the applications became immense very quickly after that point in the game. This item, like the spinner opened another place for innovation in gameplay and world creation and sidequests. Scaling walls whith no floor/ground became exciting, fun, and a challenge when put in the right context. If you hadn't guessed this was my favorite item in the game.
Gale boomerang: Again this item was not new, but received an upgrade of sorts. It did not change in function, but in properties of that function. Like the claw shot it received a little more explanation to how it functioned and ultimately allowed for different uses of the boomerang. Fore example, put out torches from a distance.
Dominon Rod: Very creative. Not so much used as a weapon but again, more of a tool, having the object you possesed function as the weapon. This weapon again made numerous openings for sidequests play.
The only thing I could agree with you on having poor weaponry would be the requirement of the right environment to use the item. The Clawshot, spinner, Dominon rod, and in some cases even the ball and chain were dependent on the environment for their use. But other than that, I stand beside that TP had some VERY innovative weapons.
