Sorry to hear that the controls didn't work. Are you referring to the WASD/Mouse Wheel or are you referring to the dials and levers? If the former? You need to activate them first (tick the checkbox on the right of each control) as mentioned in the page's description.
If that still not working, do you see any errors in the console perhaps?
As for upgrades you need to be at the base and click on the "Base" button to access the upgrades.
I gave it another try! (I saw the checkbox, but I couldn't find it; it was pretty well hidden, haha.) But the upgrades are still incredibly slow. The cheapest one costs 80 credits, and it's taking me forever to dig just to get one at a time. I feel like a better balance of some of the speeds or purchase factors would help. I do like the interface, though.
Thanks for trying it out. The cheapest upgrade costs 45 which is an energy upgrade, I am guessing you're referring to the laser damage upgrade? That is around 5-8 hauls (for the 80 one) so it does take you time indeed. That said, maybe a slight decrease of prices at the beginning to get a quick dopamine hit would be better than have it trickle slowly from the get go.
