Thanks for the praise! Yeah, that nebula animation does look good -- too bad the whole image sequence is > 3GB or I would put the whole thing in the game somehow. However, there will be some stills from that animation series, like the one you see in the screenshot.
I haven't decided if there will be another demo per se. I mentioned a few posts up that the final game will be a free, donation-only model, so you will be able to play it as soon as it comes out. I'm aiming for the end of this year . . . but I also have a lot of business trips scheduled, so we'll see what happens. All I can promise is that when I'm at home, I put in at least an hour a day, which so far has been working well.
I stopped doing the monthly demos as it was getting a little exhausting and some months didn't have much progress. Plus it frees up more time for the most important thing: finishing the game.
Thanks again for the feedback!
