Areas has 72 levels, all designed around one simple goal: shrink away the circles that slowly fill up the screen before they suffocate your tiny ship. In that regard, it's hardly more complex than Asteroids. But don't let the simplicity fool you. Areas is a smart, surprising little game.
Buttons are overrated. It's the design philosophy behind Areas' control scheme, which employs nothing but mouse movements. To move, pull the aiming cursor away from your ship. If you want to shoot (and you'll need to do a lot of shooting), draw the cursor in close, and your ship will begin firing as it decelerates. Clicking will get you nowhere, even in the game's menus. It's a little odd at first, but it'll grow on you.
With its basic black-and white color scheme and simple line art, Areas seems a little dull at first. Stick with it. Several levels in, destroyed circles start dropping a series of very cool power-ups. They show up as mysterious circular symbols, and it often takes some experimentation to figure out what they do, and how you'll need to use them to succeed.
Areas' only sound is an eerie, looping soundtrack. It's wonderfully evocative, but if it starts to get tiresome (or you need to play quietly), just hover your aiming cursor over your ship. After a couple of seconds, a pause screen will appear, complete with volume controls.
