Thank you for the recommendations!
Aside from Taarradhin, I think the rest of yuri OELVN tend to go with simplistic style, huh? Clearly it's a far cry from Japan's sometimes overly sexualized depiction of this genre.
Some of them have been downloaded and I'm looking forward to play them. I've also played SilverHyena's Mira's Magical Mishap (kind of a fan for their easy-in-the-eyes sprites ever since their first game).
And I'm looking forward to another witch themed VN Escape from the Princess, which kind of bordering on Japan's take on yuri.
