Played the demo and I must say, it was very nice. I recognized the BGM in a matter of seconds which I find quite amusing. That rendition of Specialist is a really good BGM for this type of game. As since it's a demo I'll have to say, the artwork is very pretty and looks great with the backgrounds, character routes seem really interesting (especially their personality). The fact that you can choose the MC's sexuality is great for more options for the love interests.
8.9/10, I'll be excited when the full game comes out
