Very good demo, I seriously Hope you do continue working and updating it.
The models are good (as expected from using Koikatsu) and so are the animations. It's one of those games that has true bestiality as in, the wolves have dog dicks and the turtle has a bad dragon dick (I'll take my chances with these), the wolf even has an animation for knotting and turning around.
The combat is ok, the mechanic of seducing enemies on low health is ok, you get an attack that doesn't kill if you want to unlock a scene. Magic on the other hand requires you to press Z and X in order of appearance like a rythm game which was... less than welcome since RIP playing on one hand.
Also I had a crash when looking at the futa seduction scene for the bandit.
Also also, spark tome works as intended, you use it and get the skill but heal doesn't work, don't spend 400g on the heal spell like I did, money is kinda stingy since at most an enemy dropped like 10g, finishing the quest does give you 500g. You might want to either buff the amount of money from defeated enemies, allow prostitution, work at the inn, you know, the staples of the genre.
All in all I did enjoy my time with the game, short as the demo it is.
