Drag The Dot

This game has very simple controls: it's all in the name, you drag the dot to the goal. You just have to make sure you don't touch anything along the way. It gets hard pretty quickly.

I'm generally somewhat opposed to games that rely on precise machinations of the mouse pointer, but this one is pretty well done. It's more about planning a course than following a single pixel wide path, and that's a good thing. There are some pretty interesting level designs, check it out.
