Thank you for your review - made me chuckle. ^^ Yeah, there are multiple strategies to chesse :D.
And sorry for the red text on dark background. Maybe should have used some color blindness simulation for the browser. That might have prevented that.
Don't worry about the accessibility, it only concerns one or two lines at most in the game, deosn't hide any vital info, and during jams you can't account for every case. It made no difference on the gameplay in the end! ^^
