Personally, I was a big fan of the art style, background, atmosphere, and the animation really added a nice touch. The good ending screen in particular with a full view of Lucie also really helps the player appreciate the ending. The only improvement I could see in this department is perhaps adding some facial more expressions to Lucie when the player says something disturbing due to brain rot or during dialogue during the good ending. The mechanics themselves are easy to understand and fun to play around with, and while I think the timer and bullet difficulty is fair I think the brain rot mechanic is a bit too forgiving as it does prevent the player from getting the good ending but also doesn't change the dialogue options too much. Overall, a very wonderful and charming game!
Like the atmosphere, dialogue and music. Bit difficult to get other endings, could consider implementing a "skip" dialogue option as it gets a bit tedious and repetitive when re-trying multiple times to get different endings
