So got to the broken vase part where I pick up a key, but the game keeps returning me to the main menu after talking about taking it upstairs! WIsh I got to see the end of it though!

I'd say you have a good base for a game, for a visual novel made in unity instead of ren'py, it's not too bad! Interesting plot, I was kind of annoyed by Valentina being super worried- so good job with the character design! Vivid descriptions of certain actions too! I liked hearing about Valentina being like a pink flamingo, was very easy to visualize. Good writing! :)
