This site aims for WCAG-minded semantic HTML: skip link, labeled forms, visible focus, readable contrast, adequate touch targets, and reduced-motion support where motion is present.
Interactive visual tools include an equivalent list or table view where needed. Color is never the only encoding. There is no time limit on the tools. Classification can be revised.
If something is unusable, email hello@playbgt.com with the page and what you use (browser, assistive tech). This statement is not a conformance claim.
