Unsupported browser

The browser you are currently using is unfortunately not supported.

As of now Corsair can only be played with Chrome. In the future we hope to add support for more browsers.

Ah, I missed the demo part. that is pretty shitty of them. I don't mind if sites say "warning: we havent really optimised for your browser, but try anyway", but flat out blocking the content is indeed terrible.
