Hi! It's been great playing chess here. Could you make it so that you can see which square the piece came from when you made a move? Chess24 does this, it makes it easier to keep track of the score. And, when playing on a mobile phone, I don't hear the sound of the move being made, when playing on a computer it should be there, I've heard from a fellow user.
Sincerely, Panter Mati

I think I fixed a long-standing bug with the help of AI - playing audio on mobile. It didn't work properly due to various browser limitations.

It should work now - I'm waiting for feedback!

I also did this in chess to show which square you moved from.

If it bothers anyone, let me know. This could also be turned on/off!
