This flash seriously had problems.
1. Voices: The female voice in the flash was completely unnecessary. If you absolutely had to add voices, you could have taken the time to give the guy who gives you advice a voice. Its either you use voices or you don't. In this case, you chose to make us listen to only one voice which happened to be an annoying one.
2. Difficulty: Personally, I found this to be way too easy. All you had to do was build 5 turrets at the very right immediatly, save for power plant, build that, then just keep building turrets and power plants until you win. It didn't help that you couldn't restart the level if you failed anyway but if you have some idea on what you're doing, you wouldn't even need to. Now as for the final level, all you had to do was shoot a missile and finish each mech off with your machine gun.
3. Spelling and grammar: It's sergeant, sergeant for crying out loud! I'll let this go if English isn't your first language but if it is, you need some work. Badly
I gave you a review 5 for the effort though.
