Thanks so much for the kind words :)
We went back and forth on how digging should be triggered and ultimately settled on automatically moving into the block, another option we considered was needing to press spacebar to dig the tile you're facing, along with a little visual indicator. Sheathing the shovel is an interesting idea too! The way the shaders handle hiding blocks you're distant from and the way the background blends over all was something I wasn't super happy with and felt like it needed some polish, but we didn't really have time to try other approaches.
