If this is how people attack you on tower defence games like "Baloons Tower Defence", they must have practiced a lot to send out 50 waves of enemies...
Umm i have a suggestion. Can you lower the Cassgun's damage or something? I just blew through normal with out dieing or getting close. i just upgraded the- Master of Energy Weapons (Energy weapons do 15% more damage) - then -Fast Reload (Reload speed increased.)- then I boostes the ammo with something. Then i upgraded the rate of fire. Then SharpShooter(Increases Critical Shot Chance) all the way. Then some -Sniper-(Increases critical chance bonus). Then i upgraded the overall damage. It was instant kill almost every time. Every guy but the giant rocks. It was just a little weird. Please do something about it, or dont, i just think it is way to strong.
dude i found a giant monster, flew up to it and kicked him in the balls! then i journeyed to the moon,,,,,, nah im just hi :}. this game ismmmmmmmmmmmmmmmmmmmmmmm
