OP post has 13 screenshots. Out of them only one has even remotely a hint on how the actual in-game content might look like and the rest just show some characters with no context to them or the main character sprite standing in the environment with nothing going on. Going in I have no clue whatsofuckingever how the game is going to play.
This is a pretty common thing on here, especially with html real porn games where the op post is just a bunch of porn gifs that tell you genuinely nothing about how the game functions, and it is annoying every fucking time.
I understand that the screenshots were just pulled directly off the DLSite page, so them being entirely uninformative is the dev's fault. However, it probably would not have killed the op to launch the game and just make even three comprehensive screenshots, like the in-game menu for example, so people can tell what the fuck to expect in the game.
