Adrift was just a prototype to test an idea. The past couple of months I've been working on the real game which is now called Portstar (because there were already other games using the name 'Adrift').
The website for Portstar is Playportstar.com although there is nothing there yet (but soon!).
In the meantime, here's some screenshots from the past week or so showing some in-game rendering of a test ship and some terrain.
