Hey thanks so much for the positive feedback! Makes me feel good that you'd be willing to try it again despite the flaws. I actually think this concept has potential (with a more responsive/intuitive control type) and look forward to adding more mechanics to really build on the "mine and move" concept.
My personal best is 701, and that's with knowing where everything is and all the best routes haha. No pressure, but if you ever beat that I'll crown you king of the kero caverns. Thanks for playing!
