Thanks, my wife drew most of the assets XD. I rushed to her desperately one afternoon and asked her, and she drew the animation sprites and the void-horror for me lol.
I know what you mean by the slippery controls. I too noticed that accidentally digging a non-intended block was easy to do. It did bug me, and I really wanted to tweak it, but alas, development time was running out.
Thanks for the kind words, I'm glad you enjoyed it :)
