Two problems with the HTML5 version in Chrome: 1) No audio 2) If my mouse cursor moves off the window it loses control of the ship Flash version has neither of these problems. No idea why audio is broken. I tried a couple HTML5 audio test pages and it works there. I'm using Chrome beta 26.0.1410.28 on both Windows 7 and OSX Lion, broken on both. I didn't notice any other differences.
