Bobbing is a fast-paced, finger-twitching, reflex-hounding action platformer from Little Bobby Games. You play as a little eskimo creature whose only ambition in life is to run endlessly through a circular labyrinth filled with twists, traps and lots and lots of fire.

Each of Bobbing's 100 classic stages task you with one goal: reach the end in one piece, which is easier said than done. Your only controls are in the form of two massive buttons at the lower corners of the screen. The left button reverses gravity, while the right changes your character's color from blue to pink and back, allowing you to pass through colored walls and floors.

The level design is a work of evil genius. Passing each stage requires a heavy dose of both quick wits and quick reflexes, with portals, bumpers and barriers all adding complications that turn Bobbing into a puzzle-like experience. The challenge ramps up fairly quickly (did we mention lots of fire?) but luckily, an easy mode exists if you're not quite ready for the brutality of classic mode.

Bobbing is certainly a game that does a lot with a few basic mechanics. Unfortunately, besides collecting all of the bonus widgets on each level, there isn't much in terms of replay value beyond the built-in stages. (Although the game promises new "Endless" and "Hardcore" modes to be implemented in the future.) However, the slick, simple graphics, high-energy soundtrack and superb level design make this title well worth playing. Just be sure to avoid the fire!
