Very buggy and not at all ready for trying out. You can't save your game yet, which was especially problematic since the game crashed on me about five minutes into trying it out. I had difficulty climbing stairs due to geometry collision issues. If you try to use the 'transporter' too soon, you can get semi-stuck where it's difficult to back out which means if you quit to escape it, you have no save to go back to. Angle needed to interact with objects is finicky.
