So I bought this for the PSP. I guess it's a story game done in the style of those hentai games. You make your dialogue choices and see what kind of ending you get
The actual gameplay elements were a bit surprising to me. There's a Two Shot mode where you basically have to calm the girl down by either selecting a dialogue line as it scrolls by (you only get one choice) or not saying that at all.
The other gameplay aspect depends on collecting keywords and storing them in your O.R.E. List. At certain points items from your ORE list will show up and you can press left or right to select them. Things sure have changed since the days where you were just given a list of options to select, eh?
So anyway, I beat the game, puposefully trying to do the worst job possible. I ended up with about 14% completion, it looks like I didn't unlock any story branches. I think I basically got the bad ending where I'm stuck buying BL goods with my Akagai for his little sister. Girls start pointing and whispering, so I end up running away while my friend yells out my name. Humiliation?!
The trailer for the game:
Bonus: I wasn't able to obtain this since it seems like it's sold out, but the special version actually comes with an additional game. The bonus game is a sister maker where all the characters are your sister or something. Here's the video for it:
