That's strange, I use Google Chrome and have no issues with it. Maybe do you have a Chrome extension that might be affecting the game?
You could try a different web browser. Though Chrome usually works the best for WebGL, I tried the game in Safari and Microsoft Edge and it works, though a bit laggy., which I have a low graphics setting for. I haven't tried, but heard that FireFox should work well with WebGL.
Once the voting is over, I'm planning to release downloadable versions, which should fix some of the WebGL problems.
