Thank you, glad you liked the game and the music. PallasPalace did a great job with the music.
It's not you, the economy isn't perfect and could be tweaked. The player generates 2 power a turn, so you can't get a turret until round 3. I didn't want to give the players tooooo many turrets but didn't know exactly how much to change the income vs the cost of buildings. And I let it slide because I had to work on everything else.
