Came back and tried the windows build, (which my laptop was much more tolerant of) The controls definitely still feel floaty, which is fine, but I really wish the drill wasn't so finicky about mining blocks, You can't fit through one block wide gaps but your drill is smaller than you, so it's very easy to get stuck and need to slowly maneuver yourself out of the hole and then carefully align your self between two blocks if you want to dig straight down, which, considering that's the only way you can mine, you do. Once you get over the controls managing your moles either to help you dig super deep where there's more valuable ore, or to collect lots of ore over a large area, is pretty fun.
The difficulty curve is kind of non existent though, there's no real risk of losing any family members unless you (like me) struggled with the controls for a while and wasted a couple days, after that you're home free.
Despite my complaints I had a bunch of fun with this one, good job!
