the only reason i say 9 of 10 is because of the required wall jumps are too hard for me to pull off if wall jumping had it's own key, i would love this game, cause i could beat it. that said, as it is is also good, because, like castlevania 1, you dont rush this game. you get used to how things go. it is hard, yes, but it's the fun kind of hard. all in all, 9 out of ten.
I liked the idea of it, but fitting too many functions onto too few controls is a bad thing. I kept dying on level 9 because of the coil bouncing off of a wall and killing itself.
the game is great, but you know what people say, the higher you are, the harder it gets
just awesome, play it and see what i mean
