What exactly do you need to do in this game, just walk around the house and enjoy the moans on the second floor? I'm probably the stupidest player if I didn't find an additional scene in the game.

There's an ending to the demo. Explore the second floor, that's where all the content is. The sound should guide you. In hindsight maybe an in-game guide might've been a good idea.

Hurray! I passed! Thank you. It would be cool to see more scenes and the fact that at some points you need to look into the room is not obvious. But the concept is cool.
