Uchuforce2 is designed for shooter neophytes. You control your ship with the mouse, you're firing a ridiculous swath of bullets all the time, and there's only one button to worry about. Click the mouse to change your weapon to a powerful laser, and click again to switch back to the endless waves of bullets. A meter in the lower-right shows you how close your laser is to over-heating, so if you want to avoid an extra-long cool-down delay, turn the laser off before that meter fills.
