Pretty good, a few notes:
1. Online saves doesn't work, I lost a game with 100 drones
2. Would be nice to manually target miners, because eventually they spread all across the map, each asteroid is mined by 1-2 drones
3. Some balancing needed: the prices are quite high, enemies are quite greedy, collectors quite stupid (they may all target the same distant orb)

Thanks for playing and taking the time to comment. Currently the saves only track drone upgrades and not drone numbers, so it really more of a feature or rather a lack of one. I think it's a good point though and maybe it would respect the players time better if the game did save that. I did have an early build where the player could select specific targets for their miners but it made some of the other advanced drones redundant and I also feel it took away from the strategy a bit. Balancing does seem to be a sticking point and I do plan to address this by separating the unit costs into their own categories.
