I loved it.
First of all, I love the choice of 2D for a horror jam, it's rare!
The audio and visual design are incredible, as are the story and the choices at the end.
At first, I liked the atmosphere but didn't see the horror aspect of the game... until I found the others (their appearance once found... wow).
Then the mystery at the end...
You did a great job. I don't know if you know each other, but you should keep working together!
