Generally I enjoyed my experience. I found that I had to sort of learn by doing. a small tutorial would benefit the larger game, but I think that can be added later in development. Overall I like the idea and I think you're on the right track. There are a few things I'd recommend adding. Firstly, the enemy hives aren't clearly hives that spawn nor was it evident to me that they could be destroyed. I thought they were rocks until I accidentally hit one with a laser. Making them more distinctly different than the terrain would go a long way. Additionally, they could stand to be just a bit taller (or at least their hitboxes should be. I found myself shooting over them more often than I'd like. I think it would be cool if you could take a couple bots with you like a squad. Either to deal maximum damage or to have guards for your mining bots. Enemies got really easy once I knew I could destroy the hives. Maybe having a guard enemy that protects the hives and shoots from a distance could increase the difficulty a bit. I also found myself having trouble getting the miners to work the mineral node I wanted to and had to adjust them every time, so fixing that would help.
