I'm currently toying with the idea of releasing alpha 2 soonish to fix some of the easily fixable problems in alpha 1, primarily the exceptionally slow initial synchronizing of the asset downloader. After that, we'll have to deal with the huge problem of MH not working on many graphics cards, and that will take some time to fix.
