This game has a lot of promise! I see where you're going with it being a Dome-Keeper style game.
Found the combination of precision clicking and keyboard movement a little hard to get the hang of. It took me longer than I care to admit to grasp that I was supposed to be clicking the ore nodes! The hitboxes on the little ores could be bigger / more forgiving.
Some of the invisible walls around the house are a bit big, probably can get rid of the ones on grass and pebbles.
The AI didn't pose much of a threat. I would like it if they swarmed you when your light goes out.
I liked that we were building a robot that protected us from the AI, but I would've also liked to be able to upgrade my own character's light strength, timer length, mining power etc. As I'd like to do more activities around the house.
I think your light meter could perhaps refill instantly if you made it home, rather than slowly refilling? But depends on what activities there are to do at home
The game feel was nice, the sound effects when mining was a highlight.
I didn't like the ore nodes kept respawning near my base, prevented me from going out and exploring further.
The atmosphere and vibe were great!
