The futa feature was added at some point but i havent worked any more on it since then, its still the first buggy iteration. At some point i will refine and fix it :)
No ETA when it is coming to steam im afraid, whenever i feel its polished enough to not get terrible reviews.
It scales fairly well, some people have managed to run it on integrated GPU's on laptops but generally i would advise a 1060 or equivalent GPU for a good experience.
It works on lower end stuff but does not look great.
