I liked the overall direction and theme of the demo and I'm looking forward to more.
I liked the tasks as someone taking care of the house and then spookiness goes on.
The tasks went on for too long for the cleaning. Dropping the trash and cobwebs to half of what it is now would prevent it from becoming tedious.
When completing a task I thought the marker sound effect was too loud.
I accidentally skipped a dialogue step so I didn't know I what I had to do at the end. It would be nice if there was some objective list.
I hope you try to stay away from screaming jumpscares as the main fright. They always feel cheap to me.
