this is an awesome game!! this was missing just two things!! a final boss and an extra boss that you can fight only if you collect all health and missile upgrades! (and i did by the way!) you should have made it so when you reach the king then you have to beat his king beast! (which is super hard!) afterwards then you get the power! but if you get all upgrades then you have to fight this crazy, power hungry mad man who wants to destroy the universe and create it in his own image! (not to mention he's in a giant robot! he's also super hard to beat!) then afterward you get the power and then it ends! why couldn't it be like that? then it would be perfectly awesome!
oh and Averrath, although i don't agree with your score i do agree with some of the stuff you said!
although Dragonsoul0 had a better idea! ANYWAYS,
