Left click the red circle to begin drawing a path, and press the [space bar] to begin moving. If you make a mistake, click the circle to clear the path and start over. Green or red obstacles on the screen can be moved or rotated with the mouse. It is usually necessary to arrange a level properly before releasing the red ball and, eventually, you will even need to manipulate the obstacles while the red ball is in motion. There are no enemies in Paths, but beware of the big button marked "Menu" in the bottom-right of the screen. Clicking it will end your game and send you to the main menu without asking for confirmation(!)
Analysis: Paths puts you in control of both your position and the position of (parts of) the environment you move through. At times it feels a little bit like Super Monkey Ball crossed with the wood game Labyrinth. I especially enjoy how each level demands your attention twice: First while planning and drawing your path, and then again rotating and shifting obstacles out of the way at the appropriate time. Paths could use a bit more polish, but the game behind the ugly vector graphics and obnoxious breakbeat loop is solid.
