Universalis: Post-Jam Update!
Thank you to everyone who rated and commented on my entry. The concept was very inspiring for me, and even though I couldn't get everything I wanted to into the Jam version, I practiced an important skill of scoping small.
I'm still having a lot of fun with this title, and I've been adding improvements and more modes, including a new Sandbox mode! The improvements make the below much easier to achieve. So if you'd like to see more, the link is now added to the Jam page.

Next, I'll be working on an Objective mode with levels. I've also been toying with multi-star systems, which is interesting, but I haven't yet found that it yields stable orbit patterns. More to come!
Cheers!
