Appreciate the thoughtful feedback!
I originally started with immediate feedback that you got the placement right, before I went with the minesweeper mechanic, but I think the minesweeper one solves quite a few design issues. I kinda like the way you have to be *sure* you've got this right before you fill it out. I do completely agree with making it have a difficulty curve. On the pallete, it's classic NES. I value your opinion and I'm gonna take that back if I dig into the design further. Thanks again sir :D
