Edit 2: After looking more closely at your screenshot, the little white box in the center that I thought was blank actually has an error message that says "Please note that Unity WebGL is not currently supported on mobile. Press OK if you wish to continue anyway." This is the same error that I get. Before trying anything else in this post, just press OK and see what happens. If it works, the next thing you'll see is a loading bar. It might take about 30 seconds to load the game.

So my next question is a dumb one: did you let the page fully load? I ask because I see in your screenshot that one of the site banner ads has loaded, but the other one hasn't (it's the yellow rectangle on the right). This makes me think that the page didn't fully load, and maybe the game didn't have a chance to load. Try waiting a full minute on that page to see what happens.

Second question: do you have WebGL enabled? You can check by typing chrome://flags into your browser and search for webgl in the search box. You should see something like this:

Edit: Here's a link to my image if you can't enlarge it; I'm having trouble with imgur lol: imgur.com/a/CTUQitB


If it says disabled, go ahead and enable it, relaunch Chrome, open Roodoku again, and wait another full minute. Let me know what happens!
