The two Alto games: advetures and odessy; they look great but for some reason I've found the hard to get into. Essentially they're endless runners so perhaps that's the thing--I like to complete games, or a level, and you don't really do that on endless runners.

Another good point and click puzzle game is Love You To Bits. Each level you have to find a part of a robot that's been blown to bits and scattered on lots of different worlds. Each world is one level. There's a lot of variety in the levels I've played so far and it's not been too difficult.
