Even better. The ultimate hack that everybody has been waiting for.
Here's the hack for a one-hit kill. What it does is NOP out the code that checks if energy is less than zero, so then it goes straight to the destroy function.

Now, for strategy to use with this: First, get 2 blue turrets, and upgrade their rates whenever possible. At this point, you can send maybe 3-5 waves at a time. After maxing them out, add a couple more blue turrets and max out those rates. Eventually, you should be able to send in maybe 10-20 rates, no problem.
Now, the next thing you want is the fusion gun. Why? because it pretty much fires in a straight line, knocking down anything in its path. So get one (or two) of these, max out its rate, and now the enemies will be stopped at the beginning of the screen, no matter how many waves you send in. Enjoy!
Oh, and one more thing. Be sure to watch your kills and such so that you don't end up on the high scores. Looking at it right now, there are definitely some outliers who are obvious hackers.
