Dotsy is a fast-paced puzzle game in which the goal is to create as many moving dots on the screen without any of them colliding.
Here is a quick video of what the gameplay looks like:

The arrow in the top-right of the screen points in a random direction, and when you tap the screen a dot is created, and begins moving in that direction. With each dot created, you get 100 points, but the game also speeds up over time, and as soon as two of the dots collide, you lose. You then have the option to start over, or submit our score to Game Center.
