Hey everyone,
sorry for this. A lot of people seem to have trouble loading worlds at the moment. There is a bug, it's reproducible and I'm working on fixing it at the moment. It might take a few more hours, and I'm fine with calling the game pretty unplayable until that's fixed.
So if you want to play cyubeVR, wait a bit until there's another announcement saying the bug is fixed. Very sorry about that, this bug should definitely have been noticed in testing before the game was released.
