This my new app,and it is one of the most satisfied.
One Stroke is from nintendo ds/gba's classic puzzle game(Polarium).
Use the direction keys or touch the screen to draw a line in the board which covered with red and blue blocks. Clean all the lines if color of horizontal lines are the same for win.
