Vectors

Sympa.

It takes the concept from turn-based racing games (Racetrack / Vector Racer) and turns it into a puzzle game instead of a racing game. You move on a grid and each turn you can change your speed by 1 in any direction, so for example, if this turn you're moving 4 squares to the right and 2 down, next turn you can move 3,4 or 5 right and 1, 2 or 3 down. A little rough around the edges, but not bad considering the price. It definitely needs an option for windowed mode and some volume controls though.
