Puzzle-based gameplay meets hardcore RPG action in a rather excellent little package.

Rayman Jungle Run ($2.99, now $0.99)

If you've still to discover what the fuss was all about, the entry fee is suitably low at the moment.

Float ($0.99, now free) [No Longer Available]

Float is a game that's designed to be satisfying and relaxing, and definitely shouldn't be mistaken for anything resembling Flappy Bird.
