Okami: just killed a huge freaking spider through gimmicky means.
...ok, whoever said this game isn't "that much like Zelda" really needs to look beyond the obvious differences. Yes, combat is different, yes, Amateratsu can Jump, and yes, there are different growth patterns...
But lets be reasonable here; that's what makes Okami not a ZELDA RIP OFF. Its still very much the same style of game. You do random things, then a big dungeon with a lot of puzzles (for all that Okami is a bit more blatant about how to do them, for better or worse), sometimes item collecting is involved. You gain power ups that let you do more odd shenanigans, and you kill enemies to gain things like Health, Money, and Magic Refills, but *NOT* EXP!
There are even many of the same style of items. I mean, I got the Bomb painting not long ago, and I JUST got an art that's Not!Hook Shot...if I get a Boomerang and Bow&Arrow (which I'm doubtful of, granted), I'll have gotten all Zelda Stereotypes <.<
So, uh, yeah, the game is very much the exact same genre as Zelda, just like any self respecting game, it actually tries to be unique rather than just rip off a popular title.
THAT SAID...the game is fun so far <_<
Note: I'm aware most people basically sum up Okami as "Zelda-like", but there was one person who actually said "I don't get why its compared to Zelda much; the two aren't that alike" and that stands out. Heck, I even have several IRL friends (a few are MAJOR Zelda fans even), and they openly state "Game is Zelda-like", so yeah, I'm aware whoever said this is in the minority.
