This game is a lot of fun, but I'm having a big problem with it... I'm unable to get past level 2, because I keep being overwhelmed by the 3rd wave. I've tried using both turrets and garrisons, but my gun turrets always run out of power and my defenses are overwhelmed. Am I supposed to spam solar panels and capacitors to run my turrets for long enough, or is there something I'm missing?
Thank you!
