I really like this game, and I can't stop playing this! But also, I have some proposals for you.
At first, please add some new turrets.When I build my defences with top turrets, the game begin be boring.
Also, please make more different ways (new extructors for example) to harvest reourses.
And after all, please add more ways to protect your base : for example, new variations of energetic shield, healing turret, generators etc.
Thanks!
