this project only basically just came into proper development as of about a month ago, and all things considered mato makes basically nothing off of it (about $100 a month, probably before taxes & whatever patreon also takes), so i wouldn't be expecting any substantial progress for a good while, however it IS actively being developed regardless. Taken directly from the Rumi discord:
The plans
Next, I would like to try to develop this into something large sandbox-ish survival-ish game with a high degree of replayability. At least that's how I imagine it now. Although most of the gameplay in the demo is interacting with human NPCs in the city, in the future most of the content will be related to all sorts of fantasy creatures in the outside world.
Will it be an RPG? Nope. well, not quite. I'd like to build gameplay around world exploration and money/resource management. No levels, no skills, no obvious quests, almost no combat.
