I'm going to guess that you not being able to see all of the action in the death scenes is just because it's a demo, but besides that this game is literally Five Nights in Anime if it was unique and actually good.
This is an absolutely fantastic game from what I have seen, though I wish it was a bit more challenging as I got to Night 4 with no issues at all. (though I'm a bit biased as this checks all my kink boxes)
