Yo, this game keeps on giving! It was a nice sequence of A-Ha moments. First I deployed and was happily mining when the aliens appeared and destroyed me, my poor drill could not do anything against such reckless hatred :(
Then I discovered towers and walls, my life improved a lot, built a couple houses.
Then I discovered bot builds, made me a double drill guy, and a laser dude, lots of fun. The coolest moment was discovering I could destroy the nests, felt like turning the tide.
Solid game loop, went all the way to 10 houses!
I guess your challenge from here on is to keep scope contained, lots of interesting interesting ideas in the devlog, agree mainly with allowing units to act on their own - miners mine nearby deposits, weaponized droids act as turrets.
I think a few enemy variations could go a long way in adding depth, the player would have to set up defenses and go on expeditions to a nest of a dangerous enemy type for example.
Overall, great work! Curious to see what you come up with next!
