Space shooter game. Battle different types of alien enemies to protect your life bar.
Green aliens are normal enemies.
Yellow aliens add to your score multiplier, but be careful, if you miss you will lose the multiplier.
Watch for blue aliens! Blue aliens are bombers. If you destroy one it will destroy all other aliens in the area. Watch out though, if it touches your any of your shields it will destroy them all.
Keep an eye out for power ups that float across the screen. These will give you five multi-shot blasts.
