Just wanted to stress, that it is a decidedly parodistic comedy VN and if it has the choice between taking an emotional story scene to its conclusion and making a joke out of it, it will opt for the later. I haven't read Lamunation so I can't make the comparison yet on how things are done there, but I have read Fureraba and it felt very different in what the VN set out to do, since Fureraba tries to be fun in a wholesome slice of life kind of way (mostly) and Sankaku Renai (mostly) pokes fun at story/setting/character tropes of charagames, (and otaku fandom in general) while going through the motions of being a super basic charagame itself. The intent (as I perceived it) was pretty different and that was the main point I wanted to make, sorry if I make it more difficult than it needs to be, but for me that's an important distinction.
It correlates to charage like Undertale does to classic RPGs and Bakemonogatari does to harem anime, but without having as much insight and instead having fun with the theme in general.
