Back from comment fiending:
Again not many note worthy things to put here:
1, the game is a game meant for multiple playthroughs(is this something special? no idea maybe it means something maybe im overthinking)
2, Possibility for a dlc... will depend on the game popularity, if the game doesnt perform well BBQ will just go on a vacation, BBQ did mention the possibility of dlc content being just a free update
3, FPS game: BBQ said there were plan to release mid next year or end of year(probably this) but me personally I find it unlikely.
4, Uncensored version... BBQ cant answer this question but the steam version with saikey patch will likely be different from the dlsite version.
5, Possibly more important than the other ones... Routes: BBQ recommends playing the prince route first(supposedly this route has sufficient content BBQ could make a standalone game of it albeit only being able to price it at 1600 yen, second round should be normal ntr without meeting the prince, 3rd route should be pure love.
6, This game might be bigger than Nebel based on content.
7, The breasts drooping are either intentional or artist's choice, bbq did not do it intentionally
