Really nice game that definitely fits the theme (both Halloween and uninvited guest). I love the pixel art style! Though the character designs don’t always feel completely consistent, the visuals still work well overall especially regarding the given time! Controls work fine, while mainly using the mouse and the story was surprisingly engaging. I genuinely wanted to solve it! Unfortunately there was a bug (SPOILER): When entering the code for the piano the game showed the dark room and then froze..Nothing happened and I had to reload. However, after doing it again and getting to an end, it was a great experience overall.
The UI could use a bit of polish (color and text style). I'd use less contrast here maybe. Also some background music would have added more atmosphere. Still, considering the time limit, this is a very well-made and enjoyable entry. It’s got charm, a solid concept, and a payoff that feels earned!
