There are eight different levels to play through--each with its own boss waiting at the end. The levels all have their own theme and progress in difficulty as you advance.

Leaf Bound also features two game play modes--Campaign and Arcade. In Campaign mode, you play through the levels in sequential order; Arcade lets you play any level at any time.

You control the direction Yuri jumps in by one of two methods: swiping your finger left or right or tilting your iPhone or iPod touch in the appropriate direction. Jumping is automatic. The swipe method worked OK, but your finger can get in the way. The tilt controls worked like a charm; you've also got the option of adjusting the tilt sensitivity of the game.

The graphics in Leaf Bound are done in a refreshing anime style that fits the game. Each level sports its own unique background image that is slightly blurred for a nice sense of depth. The sound effects and different music for each level are nicely done and complement the Leaf Bound's cheerful atmosphere.

All this adds up to an entertaining game, though not one you're likely to keep coming back to over time. Leaf Bound doesn't take very long to beat, and I don't see a whole lot of replay value in it. Yet at $1, Leaf Bound is one of those games that make the time you spend waiting in line or commuting to work fly by.
