Good concept but very buggy. Selecting units, or even having them attack or pathfind properly, really didn't want to work. Spamming seems to have no downsides at all. You'll really want to introduce resources or something like that.
Very fun, but the camera desperately needs to be zoomed out with how fast you go. And don't think I didn't catch that line about the protag being rated for multiple tons; once you tease that we gotta see it.
