I wouldn't trust them to do that. The company they used produced the last (pre adventure games) Doctor who game, which was really, really bad.
I bought the Ipod game yesterday, and it's pretty decent, for £2.50. It's basically a bunch of block/switch puzzles, which have to be done whillst dodging the various enemies. Both the characters have unique abilities (the doctor can climb over certain walls, and push blocks, whilst amy can climb through passages and walk over fragile ground.). I
Also, when your character gets killed, they regenerate, which would have been a nice touch, if the same effect hadn't been applied to Amy aswell. Odd.
