I got this game from Gamefly, and after about 3 days I sent it back. I was a fan of the Lego Star Wars, and the magic from that just didn't translate here to me. The platforming aspects were annoying (Very hard to align and it is even easier to fall, which is weird considering you have a whip at your disposal.) Also the puzzle solving was not very creative and bordered more on annoying than fun. I didn't even feel like playing through just to get achievements.
I wouldn't say it is a BAD game, but it just didn't appeal very much, and with Ninja Gaiden II at home now from GF, I decided it was better for me to send it back so I have a slot open to be filled by GH: Aerosmith when that comes out.
