Art design is great! I believe I found an exploit, as every unit sell for more than what it originally costs, I tried not using it but there was a point I got overwhelmed, and I just bought snipers and sold them immediately to get lots of points lol
Funny you mention that, my friend was play testing the game just today and found the same exploit lol! Surprised I didn't notice that when play testing it myself, but I am really glad that you enjoyed it. Thanks for playing!
