Nice concept. I like the spirit and possession mechanic. I also like the portraits. And for a 2-week jam, you really put a lot of thought into the story.

The control configuration seems kinda odd though. The mouse isn't really used for anything except to possess enemies (assuming you don't use the mouse for something else later in the game, since I didn't play all the way through). I feel like you could have just kept everything in the keyboard  .

It's also kinda hard to tell who's talking. It would have been nice to have only the portrait of the person talking be on screen. Or at least center the speaker.

Otherwise, really nice game. Great job!
