When System health is less than or equal to 0, you could use a System Wait 3.0 seconds and then show your Game Over screen during the Wait period before the System Go to Layout1.
Running Windows 8 64bit, with Chrome 33 (all chrome://flags in default) and r163 build. Chrome 33 browser defaults to webgl just fine. I have Configuration Enable WebGL On. At first it was defaulting to canvas2d and the FPS was at 36, but then I updated the GeForce drivers from 331.65 to 334.89 and it works great now. I'm getting a solid 60 FPS in both webgl and canvas2d with Chrome 33.
Develop games in your browser. Powerful, performant & highly capable.
Definitely a Chrome 32 issue.
1. chrome://flags/#ignore-gpu-blacklist
