Have you tried waiting for about a minute it might take sometime... If it's still showing a blue screen it might be screen scaling issues because the home screen is also blue....what is showing on the blue screen?

I tried the device emulation modes in the browser, also saw the unsupported pixel ratio 1.5 message. It did get me a bit further when I reloaded I saw the click here to start, then it went pink with some text but was all zoomed in. Though after that I started getting font loading errors and it was just stuck again. I did load it up on my phone and had a bit better luck, but only seemed to be able to pour one color of liquid? Sounds like an interesting concept, and I'm always amazed when folks build things just with phones. I hope you work on fixing it up a bit!
