Aw thanks so much! Your feedback is heard loud and clear. It goes a lot faster when the game has access to full background thread support but it suffers on web. I have some thoughts to improve it when the build unlocks. If you leave your tab active it *will* complete eventually. The completion% is for the overall game (ie how close you are to beating it), not how far along the advance time is going. This is good feedback too that we will make more clear. Thanks so much for checking it out and the awesome feedback!
