There are some difficulties I also experienced - when played online, no problems on any system, as well as on androids. Also as node-kit-app it runs just fine on windows (unfortunately did not test Linux yet). It did run on Os X, but people tried it a lot of times to start, until it came out, it is loading awfully long, showing no percentages at all. Like 10 minutes (Also after being cached ). Also, there are some issues, nowhere else occur, but it is not easy to find the cause, since it seems all right. There could be some special issue.
