[Babbage]

the ability to hover just long enough to avoid losing a life

(also pretty pictures of German castles)

[Skull Commander]

I like the fact that at first it seems like a Pac-Man style game, but once you start playing it's so much for largely thanks to the flying element. They really got the weight correct and when you float down you gather momentum. It adds a lot to the game overall.
