This one was fun!
Nice touch adding support for different keyboard patterns (though my AZERTY keyboard was working as a QWERTY keyboard there somehow) and navigating the (in depth) settings menu with windows narrator enabled was quite a pain (though I am not used to it so it can be the reason why).
The game itself is a really good idea and fun to play, I would just want a better difference between the actual target cell and its closests in the same row.
Last thing, I could not restart a round and had to reload the page after every game
