Good
It was good, but first of all, the graphics need work. I don't mind simplicity, in fact, I often enjoy it, but a few dots and circles isn't going to cut it.
Second, the dot follows the mouse extremely slowly. It's fine after you get used to it, but I felt that this really didn't belong here, and it should follow the mouse at the same speed you move it.
You also made it so you have to touch the dot to get the game started, but the dot is rediculously small; you should have had an area like the circles to avoid to start each level. This isn't really a large issue, but it would make the game 'flow' better.
Overall, it's a fun game with some cool ideas, even though it's an overused concept. It needs polish, but it's definitely far from a bad game.
