My game had problems on Chrome too. On my latest version (I'm working on a release for after the voting) it works when I remove the Particles2D. I plan on replacing it with animated sprite since that will work with my game. If someone has found any other node types that don't work with Chrome, maybe they can reply to this post.
I plan on creating a bug report after I've made sure it isn't already reported.
Edit: The issue with Particles2D and Chromium browsers is a known issue.
