Really good stuff.
I am on a date with Sybil, who is some sort of vampire (I think). My character seems really enamored with them. I eventually end up as their pet.
I didn't run into any technical issues. The use of the background image was really good at creating some context for the narrative. At some points the candle would make the writing hard to read, so perhaps it just needs to be darked a little more.
The writing was great. The descriptions were very rich and they gave me a good sense that my character was hypnotized by their date. I also enjoyed the ways in which you highlighted the awkwardness of a first date, even though it was never ambiguous that my partner was some sort of monster. It also highlighted the differences between the two characters; one being exquisite and the other feeling out-of-their-league.
I am interested in your choice to leave things hanging with a question and initially felt quite insistent that the lack of choice was a bug (I even zoomed out the page). Perhaps it all happened so fast towards the end that I was expecting things to be drawn out a little more?
