I have a terratron that wont upgrade. Takes my money, stays level one

I just got to the third Level, and this game is already defeating me. I mean, I do not even have a fair chance with all the Ground and Air Units that you're spamming at my defenses. If you make an easier level option, I will keep the game in my Library. Otherwise, I am returning this game within two (2) days if I do not see any changes for the better. You can make harder difficulty levels for the loser kids living in their mother's Basement, playing Video Games every day and night....

Enjoying the game so far but when I enter the perks screen I don't see any way to exit that and return the to mission screen. I'm having to quit the game and then continue. I'm playing full screen at 4k. Different resolutions didn't seem to change how the perks screen looked. It seems to be stretched.

Like it says in the tittle, not a single button works when you press escape, you cannot reset, go to war room or quit the game, i have to press the windows icon and stop the game in porder to exit it!!!!

That's really irritating.
