The game's premise is very interesting and I like the idea of a horror filled chess match. But, at least in my run, I found the jumpscares a bit too overbearing.
I understand that there's no real way to gauge a player's match, but maybe it might be better to tone down some of the wall text scares and go for some environmental scares like a window shattering and etc.
I also found that the black chess pieces blended into both the board and the background when you are at the table. Maybe either lighten the black chess pieces up a bit or brighten the area around the chessboard. That's my two cents on that if anything else. Great game idea.
