I have to say IKARUGA is one of the best Shooter ever created. The game uses ying-yang system dark and light color. If the enemies craft shoot you with the same color you are using you wont die but you absorb the bullets and that bullets powerups your bomb. You can switch the color you want
Believe me or not IMO Ikaruga has the best graphics ever created till today! So clean like christals , clue ocean ! i just can describe it!
