Not to brag but this game was kinda easy. Got up towave 54 or something before I decided to not carry on anymore. The medkits are so cheap that you turn invincible when you've gotten the minigun. Should probably make it so the price on the medkits scale with the wave number. Or something like that.
I've only been able to get them to build a 2x2 square wall (house?) + 2½ tree. Last build was at 800 resources, I'm now at 32k+ resources and 100+ in every stat. Am I doing something wrong?
Read the "Game News" section about saves. Hope it helps.
