Nice cosy incremental! It reminded me of a mobile one I played a while back, but with much fewer ads, haha.
I hit a rather unfortunate bug where if you open the upgrade menu on the day of a new quota, you couldn't leave it (refreshing fixed it, good thing you added autosaving!). It's kind of a shame that lower depths feel the same as higher depths, I would've expected bigger ore patches and more than 1 new ore by 500m depth. But the art is great, the music is chill, and the game is fun - great job!
