Horrible, ambiguous ending. Cowardly.
I have the physical volumes. In the author's notes, it's stated by the mangaka that he just wanted to write a story based on his love for old school arcades and the publisher convinced him to turn it into a harem romcom. I'm glad we got what it ended up being.
My only wish was that the 3rd volume kept up the ecchi depictions, but it quickly started censoring the nipples for whatever reason. I also wished there was more with the 3rd girl, but mangaka wanted to end it, which is fair enough.
Overall, the story was okay enough while the visuals mixed with fantasy depictions of them in the games that they play were pretty enjoyable. If it ever got an anime (honestly doubtful) If hope that they expand on that part. It was a pretty fun romp, but did leave me wanting more.
