It saddens us to bring you this news, but CoU is no longer working in Google Chrome, our browser of choice. This is because Chrome is no longer supporting a feature that Polymer (which we heavily rely on) uses. CoU will not run on Chrome for the indefinite future, as resources are very limited.
From this point on, Mozilla Firefox is the browser to use in order to play CoU. Unfortunately, the game is very choppy and somewhat slow in their browser.
Thanks for your understanding and sorry to have to bring such bad news.
