Awesome game! As I described it to a friend: A little bit of Anno, a little bit of Factorio, a little bit of Tower Defense, a little bit of Surviving Mars, mixed in with a healthy dose of Starship Troopers.
Graphics are smooth and easy to look at, runs great on Linux Mint 19.1 with an Nvidia GTX 980.
Keep up the good work! Looking forward to future developments.
