OH MY GOD! you are crazy! there is no random! the game is preset and all that happen is every level the same but with higher speed so all you have to do to win is to remember where you must be at which second, and at lvl 8+ particles jump throught you most times!
the suggestions ppl written are very important but i should say that i played it long (when i finished i was second in all-time hiscores) and from level 5 its not a game about catching blue circles its an automat for randomly fired circles and all you have to do is hope that some of blue ones hit you because they are so fast that its impossible to catch them, maybe you should fire more circles instead of speeding them so much
flamewolf you just need to build bunker and ion annons to all adjacement pieces, build three bunkers that way than research economics, robotics and then the nuclear fusion build nuclear missiles and next to them repair center, upgrade bunker and fully upgrade missiles, fully upgraded ones are way too powerfull
