I think the concept is certainly unique. Being pulled back by a magnet while attempting to obtain batteries to increase your speed is pretty cool. I do however think that zooming out the camera and making the batteries have more of an impact on the speed would have helped the game. As it is currently they feel like they have an almost miniscule speed increase for each one you pick up. I was even able to finish levels while picking up less than all the batteries.
The music also seems to restart for each level which is a little jarring, and even with the max speed with all the batteries the magnet starts to feel rather annoying. I do however like the art and other than that the movement, while a little slippery feels pretty good regardless.
