I really like this! I only have 2 complaints. 1) I wish there was a slider for screen sensitivity, it moves a bit too much for my taste, but it's not that bad. 2) I think either the enemy should attack less often or there should be a way to heal units. I'm really bad at strategic video games, but on the beginner level I find it hard to fight off the enemy, especially if I only just survive and have to re-build up my forces and then they attack stronger again.
This all being said, I'm having so much fun with this game! I spent like 3 hours on it yesterday and it would've been more but I got busy. I'm excited for what this game will become!
