Well I dl'd mainly cause the description and screens were pretty much nonexistent, also people reported not being able to run the game. Also in case anyone else missed it like I did, this is a visual novel.
I held down control for like 5 minutes to see where it'd lead. Pretty much main character books a trip to some ancient castle hotel with the wife(?) for a potential honey moon(?). Wife gets called away, op wakes up in another time(?), gets tricked by a pair of lolis, who then turn him into a girl that ends up being a clone of some lord's wife(?), idk it's hard to follow along with the story when text flies by. But seems like you swap back and forth between this alter reality and present day, where present day you're slowly transforming into a girl vs immediate in the altered reality.
Either rate, it's voiced think fully, the scenes aren't bad, translation's decent/good. Gameplay's nonexistent on the account it's a visual novel, but there's probably a decent amount here if you want the story.
