It's been a while. Too much has changed to go through it all, so instead I'll just say that Omnifactory is in a feature complete state now. Every mod, every recipe change, and every quest is implemented. Its 100% done.
The last phase is just to do a final playthrough to catch any last remaining bugs or balance issues and then it will be in its final release form. I'll be starting that tomorrow, but I'd love it if you played along with me!
