For a first game made in unity, you did okay! Although there's not much to do, I believe you've taken the first step as a developer by joining a game jam! Your game didn't have much bugs, and although controls felt a little janky, you did okay for a first game- and a 3D one at that! :) this concept seems to me like it can grow to be some sort of survival game in the future, just with different model assets- you did not do too bad for a first game jam :)
