It's definitely got a lot of the vibes of Oni Bath House, but in an action themed format. The 3D art is gorgeous once again and the intro sequence is both interactive and cinematic which is very neat to see! Unintrusive dialogue boxes and font choices match the mood well.
Audio design felt right, the music set a properly mysteriously mischievous mood and there were sound effects for everything I'd expect to have them.
In a game like this one, running should be the default movement to free up a finger. The slow strut is a really sexy animation, so perhaps there could be a gameplay effect to give players a reason to slow down.
You have a real talent for creating visually immersive 3D worlds. What a beautiful first demo!
