This reminds me of 3 of my favorite games of this genre A LOT.
The animations are very very good. they lack a bit of variety(eg. as of yet no FJs), for me personally but thats my only gripe with them. The Girls on the other hand have a lot of variety. and I like most of the ideas that are being explored here. There is not much here yet, but from what I found I´ll definitively keep watching this thread. The demo has made me excited to see where the Developer will take things, what new enemies and animations will be added. Your player character will probably be on the silent side, there is actually no dialogue at all in the game as of this review, and there is not that much to explore beyond getting a general idea where the game is going and checking out some enemies. This demo comes with a Gallery(walk right at the start and interact with the mirror) where you will find some enemies that do not have a reachable room yet.
My overall judgement is : A LOT of potential in this one
