Shared Beauty is exactly what it advertises itself to be: a dark fairytale with no happy conclusion (I think? - I got 3 out of the 4 endings, and they were all very sad). This isn't a bad thing at all - it means it got across its tone as intended.
The character art is lovely - especially the CGs. I love the way the key visuals in the game were rendered: they felt very professional. And speaking of visuals - the cinematography in this work was lovely too. I could tell you really used the Ren'Py Action Editor well here - especially in scenes with little gestures like Isgard, Faralda and the other village girls walking to Odan's tent.
I genuinely wonder how you did it - because I've begun using the Action Editor itself and while its a very useful tool, it can get very... fiddly at times, haha.
I also think the presentation of the in-game UI adds to the "fairytale" feeling - with all of the dialogue and descriptions taking place in one NVL window. There aren't many NVL-only titles for jams like these, so I'm glad to see this form of visual novel get a bit more love.
On the writing front; I do really like the central themes of beauty and envy, especially when it comes to Faralda. Faralda's beauty makes the other village women jealous, but she's a genuinely sweet and thoughtful girl... which makes seeing her fate in some endings all the harder.
All in all, well done! Thanks for bringing this title into the world.
