As we say in the installer's licence file, for the time being, we're asking that you guys refrain from sharing this build with your friends, or publicly posting screenshots, youtube videos, etc.
Things are still more than a little rough around the edges, and we'd like more time to polish the game before sharing it with a wider audience.
Feedback and constructive criticism of all types are very welcome, of course, but for the next few weeks at least, we're asking that you deliver said feedback via this private forum.
(As the beta testing group grows, I doubt we could stop people from sharing content even if we wanted to, but, with such a small group, I'm hoping we can keep things private.)
