It is better, but still hard to make sense of. As you progress in the game, all squares are somewhat contested so everything is colored, which makes everything hard to evaluate. I like the idea of making a square brighter once it has more pieces looking at it, but having the whole board colorful like that is weird. Perhaps each square could have a number, like +1, -1 or +2 to count pieces looking at it.

Also, sometimes you see a red square around a piece, but it's not clear to me why. Is it present only when it is unprotected and an enemy piece is looking at it? That is kinda already too late, perhaps every unprotected piece could have the square around it.

And please give proper indication of what was the last move. I know most games will do this by coloring squares and you can't do this here, but having a way would be great, even if it was listing the move with chess notation below the board.

Also the pieces are a little weird to distinguish. I found myself trying to move Black's bishop twice.
