I love the concept behind this! It's so unique with the concept of possession and how you can get rejected if you are too forceful that I thought was really interesting.
One small critique I have is regarding the puzzle. I found the ending after trying for awhile but I would've found it a lot more helpful if you can somehow restrict where you can go based on the stages of the puzzle, that way you can't skip ahead to where you aren't supposed to interact yet.
I also really like the dialogue, it's very cute lol.
