The graphics are excellent. The mother ship is very detailed and features a light running across it. The sky is filled with pulsating stars that sparkle and change color. When you press the red button to suck in the space creatures, the effect is magnificent. You can actually see the creatures slowly being transported into your small ship. But perhaps the best effect occurs when you have been defeated. The screen explodes in a mass of colors and your ship is seen flying away into the night. Since so much of the game involves fast movement, there may be times when you become frustrated with the joystick's limitations.
Ultimately, experienced gamers will want more of a challenge than is offered here. After a few good plays through, even novice gamers will want more.
