This was an amazing game that I thoroughly enjoyed playing. I'm thinking of trying to get all the upgrades first before going after the evil red sun or the yellow (what I can assume to be) secondary evil stars. The smart missiles were a must have to go straight for the yellow secondary evil stars so the missiles could attack minor baddies. I just focused all fire on the yellow secondary evil stars and my allies pumped all they could into the red evil sun as well as my ship. Upgrading allies and cannons will really help in defeating the enemies. Your shield is imperative as well. The engine is helpful for keeping up with the enemies so you can keep attacking and you wouldn't be left behind the group. Overall I could play this game over and over again day after day. 10/10 IGN would rate
