I liked this stage a lot. I never really got lost as there were many things scattered around each area that made each one stand out, as well as the signs that reminds me where I can go and where I'm at. The music is really nice as well.
The boss took me a couple of tries, but I think it was pretty fair for the most part but sometimes it's impossible to continue without getting hit if your movement was poor and it doesn't really indicate you in an obvious manner what exactly you did wrong, so you have to definitely be using a lot of critical thinking which is questionable for a NSFW game, but I don't personally find it frustrating.
My favorite part was the platforming in the corrupted part, I really enjoyed figuring out how to reach certain areas, It got me in the habit of looking carefully which is definitely a good thing for a game like this to do I think.
