Steam Store description

"Uncle Otto's Mansion" is a narrative-focused exploration game. You play as Audrey, who has just inherited a mansion from an uncle she never met. Step inside and explore the mansion to unveil the story of what happened to your uncle Otto, his butler, and this oddly creepy place. 😬 Gameplay Features: Freely explore the environment, uncovering secrets hidden within every room. Inspect your surroundings closely. Search through drawers, cupboards, and forgotten corners to find vital items and hidden keys. Progression is tied to your keen eye. Find specific keys and tools to unlock new areas and delve deeper into the mystery. Discover and read scattered notes, letters, and diaries left behind. Every piece of text holds a fragment of the story, allowing you to piece together the overarching plot at your own pace. A Message from the Developer: This is my first-ever game, and it is very short and simple. Please be aware that there is no save/load feature in the game, as it only takes 50 to 80 minutes to finish. Because it is such a short experience, I decided to release it for free. If you enjoyed playing the game and want to support me, you can tip me by purchasing the "Supporter Pack" DLC. Thanks loads in advance if you do! ☺️
