I can see some potential for this game in case you wanna improve it later.
At first I thought the game had a bug, but then I realized I needed to repair the robot inside the tech store before starting the mining. I don’t know if I was dumb or if it really wasn’t intuitive though. I also think the fuel finishes too fast, I can barely dig down and already have to fly to refuel it. Maybe if the upgrades were faster it would be less frustating.
I liked the idea and I can see how this game could become very fun with more development time, I wish you’ll keep working on it! If so, I’m willing to test it again 😁.
