If I am not in full screen I have no problem ^^ But, in the non-full-screen case, the itch.io page scrolls down, when I did something. Sorry, if my comment bothers you, do not hesitate to explain to me in details how your game works!
it is not my game. Im just letting you know. When not in full screen you cannot see the pattern to match. So that seems like a webGL issue.
Oh my bad, I thought, you were the author! Sorry! Yeah, indeed, it is a WebGL issue. I will edit my comment thanks!
