Very nice particle effects on the block breaking. I wanted to do the same with mine, but didn't have time to. Still, it wouldn't have been as elegant as I saw in this game. Love the pixel and sound as well.
Mining was fun, and figuring out which blocks to make fall to leverage for hire blocks was engaging. At first, I spent all the gold towards mining speed, until my lantern fell short the next run XD. Didn't realize the lit radius decreases as well.
This was a charming, fun game.
