Let's be honest about what this is and isn't. Limina is not back in active development. There is no roadmap, no milestone chart, nothing really.
The goal was smaller and, we'd argue, more important: make it playable and keep it that way.
Games rot faster than people think. Engines update, formats fall out of support, cloud assets are gone, and one day a project that ran fine won't even load. Every year Limina sat untouched, the time cost of reviving it goes up, until eventually nobody bothers. We revived Limina now so that future days still have the option for people to play cuz why not.
Preservation important for that reason.
