The concept is the simple old minesweeper, well implemented. I love the swine addition, occasional snoring and the charging boar if you find one. Has nice music, looks simple and good.
The intro text is a bit difficult to read and i wish i could zoom out further to see the whole field top to bottom, the moving around does help out here though.
I think having the sprites tell the numbers instead of an overlay would've made it more immersive or themed.
