I really like that the board gets wiped after getting 8 pairs so you can keep going for as long as possible, it's a fantastic detail for a game like this! By the way, what did you use to make this game?
I use p5.js (processing). Source code is in the openprocessing site. It is supposed to be linked in the menu...
sorry for late response, it seems I get no warnings when I have a comment.
I used p5js as you can see in the description ( can't you?)
