Glad you enjoyed the game and thank you for your comment.
I only had a short time to add in the story towards the end of the Jam, so I know it's not the best. I focused heavily on the gameplay and mechanics. It was my first for a lot of these mechanics (placing buildings, adding story, working with NavMesh). I learned a ton and have a list of more things I want to study so my next project is even better.
My original vision for the game was to have it be more scary for the player. So I wanted them to have low resources and not a lot of time to get ready and low visibility (but the camera fog looked terrible and I didn't have time to learn volumetric fog).
