Are there humans in Zelda

Yes. Skyward Sword games saves can be copied to an SD card. They take up one block of memory.

Keep in mind that that game saves are locked to your region. From Wii Save:

We're nearly positive you can't use foreign saves on your Wii. We're still looking in to a way to do it, but so far, it's not looking good. You'll most likely have to stick to your own region when swapping saves.

As long as the Wii you use is in the same region as your Wii at home, you should be fine.

I've downloaded a couple of Wii save files from that site, and never had a problem. I've never tried to copy between consoles, though. When copying saves, you have to delete any existing save files from the destination before the Wii will copy anything. It won't overwrite.

From what I understand, there are 4 "basic" attack types in Skyward Sword:

• Vertical Slash (this can either be to the right of link's body, or to the left, depending on where the sword was when you did this, and this can be up or down, for a total of four variations)
• Horizontal Slash (two variations)
• Diagonal Slash (Four variations)
• Thrust (one variation)

In additionally, there are the two stamina-powered spin attacks:

• Horizontal Spin Attack (two variations, inward and outward)
• Vertical Spin Attack (two variations, up and down)

Finally, there is a 'final blow' attack that can be triggered when an enemy is down. Swing down both wiimote and nunchuk while Z-targeting to trigger it.

The animations take your sword's prior position into account, which might account for some of the variation you're seeing. With 3d animation, there are no "frames" like you would get with sprites. So the "animation" might look a little different depending on where Link's sword was initially, but it's not to the point where "sword down and to the left at a 40* angle" gives a wholly different animation than "sword down and to the left at a 42* angle", even though these could potentially look visually distinct.
