Woow, I love seeing fps games in gamejams. They are hard to make from the start and quite a challenge. I loved shooting the zombies and protecting my tree. Small feedback if I can. The zombies could have random speed. That way when you try to move away from your tree, it's at the risk of having a zombie rush at it and destroy it. Loved that game, you can be proud of what you made is so little time 😄
