I made a minesweeper, because why not.
To play the game, you can simply play in browser or download the GB file from my itch.io page: https://danirod.itch.io/minesweeper-gb
To build the game, you will need to have GBDK installed and in your PATH, properly configured. Then you can build the game using
make
The generated file will be in obj/minesweeper.gb.
