It's decent for an early demo, but the combat mechanics are not really there yet. The parry fails to stop attacks sometimes, and there isn't really much to think about apart from watching for that attack. Having text for hitting things in the environment is really nice, though.
Writing is a bit too random; I liked the bits with Pudica, but most of the other text just seems like complete nonsense in a bad way.
I feel like you could probably go for a higher resolution and detail when it comes to the sex scenes, as it stands it just isn't all that appealing.
