Pretty nice work so far! This is coming along well.
Just a couple of crits, and I hope you don't mind. Far be it from me to criticize your art, bit the wall slide looks a little odd with his hand and leg sticking through the wall. maybe you could tweak the sprite so that his knee, shin, and hand are scraping along the outside of the wall, rather than passing through it? Just a suggestion.
Also, the giant sword sprite always being visible looks a little strange, like it's just tacked on (which, I'm assuming it is
). Especially since it's always on the far side no matter which way you're facing. It's like it just sort of floats along next to him and doesn't really look like a part of the character. Maybe you could make a more subtle scabbard that straps to his back, that way it won't stick out as much (uh... literally I guess).
Maybe I'm just being nit picky, but the game looks good enough that nit picking is all I have to offer
