Thanks! I am aiming to have first a playable prototype by December, and when I do get that prototype I'll be putting it up on Itch.io, but it's such a large project I'd feel a bit disingenuous submitting the game itself to the jam. More likely I'll do a side thing, like a building generator or a more advanced map generator in the same engine. Or, depending how far along the project is, maybe a walking sim where you generate a world and are then plopped down into it in first person (this already works, but the world isn't populated with very many different kinds of objects right now).
