Very polished and fancy. Particle systems look super sweet.
One small issue I noticed tho is that opening and closing the pause menu either with esc key or clicking on "resume" does trigger a webgl error.
Thank you very much for playing it and I'm happy you liked it. I'm sorry to hear that it gave an error... I use Firefox on a Windows Notebook and an iMac. and I have no problems, maybe this will help you.
