Quantum Conundrum.

I have this on XBLA, has anyone played it yet?
You can switch dimensions at the flick of a button, changing the properties of the items around you and the environment.

It's a little like Portal in it's "mansion full of puzzle rooms format" and comic narration from the Uncle.

I definatly recommend you try the trial game, it's a mash up of levels from the real game.

It's very funny and enjoyable but there is a good challenge to be had too.
