Just played it. I actually really like the concept of it all, the whole isometric levels and horror-themed-but-horny enemies feel solid. The big animations are really well done, there's clear merging of sfw and nsfw into the game's format so it's neither just a game with a gallery or a game with CG. The combat is passable, but most importantly it doesn't really feel cheap or frustrating.
Only complaints I'd give is how scuffed the overworld nsfw animations are and that the pigtails enemy is kind of weird to avoid getting hit by. Everything else is fine though, just the leech enemies don't do anything despite that leech sleeve thing spawning them like boss minions.
I gotta say... for a 1.00 release this has some huge potential. The costumes/rebirths could be added to the big scenes, the combat could be adjusted just to give you a dodge roll of some sort, no need to make it more complicated than that though, the slower pacing this has is a change. Obviously more varieties of enemies you can make fuck with would be great, and I'm hoping the small leech enemies get scenes too.
