Since there are no other reviews at the time, I'll do it.
Sadly, this was so short that there is barely anything to comment on. I understand this is meant to be a demo, but I'm not exaggerating by any means when I say that I spent more time downloading the 200 MB file than playing the game.
There is literally roughly 30 seconds of playtime in this demo. No h-scenes, barely any dialogue, not even the slightest nudity. The available content isn't nearly enough to entice the player to try the first actual release which seems to be already paywalled.
If there was anything good to say, I guess the renders are good, but even that is a stretch since there are very few that you can actually see without blindly paying into the author's patreon.
