Aquastyle’s thing has always been good(for doujin) production values with absolutely no originality. They’re that kind of developer.
The weirdest thing they did was like… they released a platformer a year or two ago. Super cutesy Aya/Momiji thing.Here’s a trailer. Yeah, so, that’s real cute looking, right? I watched someone play through it under the impression that was what the whole game was like.
And then he got to the final stage, where it abruptly took a hard turn into body horror out of nowhere. (sorry, couldn’t find a video without talking over it, but skip around to get the idea.) (edit: particularly around 5:00 onwards, jeez)
Guy ended up not clearing the game because it creeped him out hard.
