cool demo, although the protagonist (Jasper) could use an angry sprite. especially during that room at the end of the first dungeon or after that scene with the rabbit summoning a demon. Jasper was just :D while he was yelling.
There's also problems with looping the animations in the NSFW scenes.
This is the demo so any bugs might be fixed in the newer version of the game. So if it is, then ignore previous critiques.
Overall a fun concept with wonderful art! and a nice hook and direction for the story.
