It's basically just Galaxian, except instead of focusing on killing all the bad guys, you gotta kill all the bad guys AND you have to keep saving this doofus king from getting kidnapped by them. It may be a bit too similar to Galaxian for my liking, but I did like the change in strategy, and how instead of you losing lives when you die, you lose lives when the king is captured. Although, I could do without him constantly saying "Help", which does get a little annoying after a while.
