My first thoughts on this app are super positive. It’s a lot of fun with a good concept. But it does feel like it’s a bit barebones. I really can’t wait to see how this game develops. No big bugs found yet.
Suggestions:
I would love to see some ways to customize the troops, like how they look, and what weapons they use. And maybe a more aggressive ai for the enemies as the levels go up? Super good job though.
