I really liked the athmosphere of the game. It felt very moody and eerie. I think you nailed the abandoned and desolate town feel. I also liked how you made a roaming storm the "enemy", it fit the jam theme and the mysterious vibe.
One thing I would have liked to be explored more was how the player can interact with the storm. Currently it was very much a "Avoid the storm or you eventually die". So if you had more time I would have encouraged you to explore things like "What can the player do when caught in the storm to get out of it?" would be a good starting point.
It was also very hard to figure out what I was supposed to do in the game. I eventually found the book after having died once. Think about how you lay out the town and the important objects to make it easier to both navigate and make it easier for the player to make decisions of where to go. That way the player won't have to search randomly until they eventually find something.
Overall, I think you did great, keep at it!
