I'm glad you had fun! ^^
sorry to hear about the audio being a bother to you, if you'd rather play with the sound effects lowered you can change it in the settings in the bottom right in the main menu, so you can really celebrate your win along with Coots! :>
we've heard a few people find chess hard, it's made with Ludwig in mind as he loves the game a lot.
Ultimately there is only one colour that can checkmate, being white ^^
regardless it is perhaps a steep challange for a lot of people, you can @ me in the Discord if you want the solutions to give it another shot without the chess being a hurdle!
