Downloaded the demo and played it, and it's pretty good. However, there are DEFINITELY some improvements needed.
First off, register Game Maker. It's cheap, it's worth it, and in order to make the best game you can, it's definitely a necessity.
Also, rather than using separate objects, use one object with variables defining what the player is doing. So, when the player slashes, set "slashing" to true, or something like that, and in the move events, only move if slashing is not equal to true.
Some of your sprites are inconsistent or don't line up. For example, Link moves when slashing his sword, and moves back when finished.
Also, the spin attack could do with some touching up. Like I said in your "making sword fighting original" topic, I think that spinning should be executed by using a combo of the regular sword button, and then the left or right key. I do like how Link slashes in different directions depending whether you are moving left or right, though.
All in all, the concept is nice so far, but the programming needs some serious work. Keep it up.
