I wanted to make a game that could be played without vision. I didn't quite get there as you need sight to navigate the menus and read the helper text, but the core gameplay can be played completely with your eyes closed
It's basically Minesweeper but inside your keyboard. Press a key, and the amount of beeps you hear correspond to the amount of mines that surround it. Press every non-mine key on your keyboard to win.
Created over a weekend in GameMaker Studio.
