Right before 3 waves before the boss comes right click and press play it will take you straight to the boss with a lot more robots use at your own risk you might restart right there.. It took me about half and hour to beat the game
To have a good defense... once you get your turrets wait till the end of the round.. If you survive... use the barricades and that will be a wall to your turrets so they last longer..then you slowly build that into a great defense. I got bored and killed myself but i got a score of 19 mil + and who knows what the score could have turned out. Try it out for yourself, you will be seeing red all over your screen ;)
If there was an option between 2x 3x or 4x your towers couldn't kill all the of them and then maybe you could have placed something to stop them.. or you would just lag a lot then freeze your cpu
