Thanks for trying out my game! Yes, I did create the graphics myself. This was the first time I tried my hand at 3D modeling, so I went for a low-poly look to keep it simple. I looked at some of general tutorials for Blender, and after getting a few under my belt to understand Blender and the interface, I moved to just videos on how to make low-poly objects like trees, rock walls, and other low-poly environments. I learn best by doing, so after just following these videos to make these objects, I was able to apply what I learned to make things like the lanterns and the door completely on my own. Finally I had to learn how to take these models from Blender and export them to Unity. I hope those links help you out!
