It's an interesting situation that I find myself in as the product is no longer only about me, as it's now supporting 5 people (and eventually some people on a part time basis - sound, music, art, localization).
I'm certainly open to ideas on how to convert Universe Sandbox to a free to play model that generates a sustainable income for continued development for years to come.
And the announcement I mentioned earlier is still coming, but was delayed a few weeks more than I expected.
