my name is Emmanuel and I have a German Visual Novel wiki called Visual-Novel.de where everyone can list and review visual novels.
Some time back I also made my own visual novels, 2 of which I have also uploaded here (one is in English and one in German). However I originally created them almost 10 years ago, so don't expect something mind blowing... but if you like them, I might start making new ones again and make longer ones ;-)
I actually also have an unfinished one that I uploaded onto here as well... I conceived it 8 years ago and was gonna call it Yandere Simulator (this was years before the other game with the same name). The idea was to eventually make it into a Facebook app and have the Yandere stalk you on Facebook - in the end this wasn't possible anymore as Facebook restricted developers too much to still pull that off.
I also have a more general German wiki called Simplepedia.de
Dark and atmospheric Visual Novels (as opposed to the more common lighthearted, cutesy, romantic Anime style type)
