In Fling Theory, you follow a particle through a journey of attraction, repulsion, destruction, and everything in-between. It's a physics flinger in the truest sense of the word.

Each stage involves guiding your partcle through series of mazes and pipes, collecting the three stars and plenty of coins along the way. By changing the charge of your particle (yellow for positive, red for negative) you alter the way charged particles in the environment affect your path through the maze. By dragging your finger towards where you wish to travel, the guide marker will bend to show the effect that the electrical will have on your trajectory. You may need to adjust the charge of nearby atoms, or even change colour yourself, to make it to the end.

The idea itself is pretty strong, and some of the stage designs make good use of the physics. The presentation doesn't really hold up its end of the bargain, however. The music is repetitive and wears you down pretty quickly. Plus, while the combination of 2D and 3D visuals seem initially appealing, crude character animations and style inconsistancies spoil the overall effect.

The biggest annoyance is that if you touch the atom and then decide you need to alter its charge, you must fling it to its death and turn some levels into tedious exercises.

With a little more polish, a few more music tracks, and some gameplay tweaks, Fling Theory could be a very enjoyable experience. It has moments where everything comes together and the brilliance of the core concept shines through. Unfortunately, these moments happen a lot less frequently than they should.
