Alright, first May Wolf I read, let’s go!^^
The atmosphere is quite well done. I liked the backgrounds having different hues, that and the music complimented thed vibes in the writing quite well. The sprites are pretty simple, but they work. It’s a bit distracting not to have a sprite for Micheal (or is it Michael?) as he is a pretty critical character, but that’s understandable.
There are some typos and stuff, but the overall writing is good. I like how what exactly Micheal’s deal is is understated throughout the VN up to the “lie” ending. Only when Lucy gets to talk about it does it get cleared up.
The folklore angle is a comparison between the characters and gods from Greek myths: Mary is Hera, Micheal is Zeus, I suppose Lucy is Hestia (don’t remember much about Hestia). Pretty simple, but it works. And the title is a fun, if slightly common, inversion, since Mary the sheep is the titular “Wolf in Sheep’s Clothing”. Good stuff!
Overall, I liked reading this, good job!
