Simple graphics that suite the game very well and great use of the theme and special object.
The biggest downside is that the game only ends by bad luck when the blue brush cuts you off and doesn't leave you enough space to outrun the red brush. It would be difficult to make it so that the blue brush "knows" what line to draw to make it challenging but still possible I guess.
Still I had fun grinding the game until I got at least a place on the leaderboards (though I'm not sure how long I can cling on to last place :P)
Great job !
