Okay first of all, this looks absolutely incredible. The models and environment are excellent. I can see this turning into something really fun once actual combat gets implemented.
I started having some massive framerate problems, starting a few seconds after arriving at the pool and slowly getting worse, to the point where even getting through a conversation was difficult. For some reason, it completely fixed itself after Capricorn gave me the guns. Something to do with the portal, perhaps?
I also learned an important lesson from this game: Don't jump in outer space.
