Is this mod still actively updated?
YuokiTani no longer plays Factorio, since November 2024 - jatmn has taken over maintaining this mod for YuokiTani.

Where is the tech tree?
Sorry, YuokiTani never created a tech tree for this mod. One might be added in the future; however, due to the nature of the mod elements, progression currently would be quite broken.

Will you add a Yuoki Planet for the Space Age DLC?
This is something I do plan to add eventually; however, I am not sure if I want to try and make it a starter planet or a blocking planet (you would only unlock Yuoki resources from the planet, for example), or if I would make it a Planet rich in Yuoki resources, such as liquid Unicomp covering the planet.

Can you update the graphics to a higher resolution now that the game supports it?
Sorta? But not really. Besides AI upscaling, that would be the limit of what can be done, as I don't have access to the original image assets.
