You really have a knack for drawing backgrounds~ I was quite impressed by the amount of detail you put into them all, not to mention you opting to draw them all in the first place (vs. using stock photos or the like) despite this being your first VN! Having the character sprites all change color to match the current background was a nice touch; it helped everything to feel visually cohesive, heheh.
As for the story, talk about a cliffhanger of an ending~ I hope we get to see what becomes of Deca, her dreamy alter-ego, and her mysterious stalker (as well as her date, of course) someday!
(also, I'm craving pasta now, heheheh)
