It's a really beautiful demo. The effects are stunning. Zooming out and watching the stars which look as they are glitter is quite magical. With the ability to visit any star in the galaxy i found myself plotting a course towards the most peciluar stars i could see near my system. Even in this early version i was still able to find a lot of unique looking planets.
As it's still in early alpha there aren't a lot of issues to write about. The demo's perfomance isn't really stable at times. When using epic quality the demo runs fine for me until i leave the starting system. Also autocolonizer really degrades perfomance. I think it would me easier to navigate systems if you could click on systems with the lesser zoom. A "travel home" button would be neat.
