Musumama6 has by far the best art so far. If you go back to Musumama2＆3, it it used to be that 80% or more of the CG would be quite bad, with some big derpiness and major anatomical problems, but here there’s comparatively very few problems. It’s a huge improvement.
The writing is also better. Musumama4＆5 had some half-assed setups that were too quick and had no feeling of taboo (which is a core part of an incest story), and in 6 the setup takes its time better and there’s more interesting scenes. I still would prefer if the mom was more shy, like 2 and 3’s, and I would love it if they spent more time on the setup because it’s the most exciting part, but this is the best story since those games.
My faith in the series has been rekindled. I hope it keeps going!
