Super Castlevania IV - Slogra, Gaibon & Death

I wanted to make some videos of this awesome game, and here is the first one. I just love everything there, the music, the level design, the bosses... Slogra (the first one) killed me a few times, and then I got an almost perfect run on this boss o_O' ! As you can see, this is the japanese version of the game (original name "Akumajou Demon Castle Dracula", not sure about "Akumajou" though =/). There are several differences in this version such as the title screen and the blood on the floor ...
