Help this 3d project

Hello, how to open the most suitable project to practice about the particle system? I always open it as 3D URP, but I watched a tutorial today and in an example he did there, you feel that the camera is 3d while the object is turning around, but when I turn the camera, I don’t feel like it is 3d, it feels like 2d all the time. The object is constantly looking at me wherever I turn it. Yes, even when I press the right click and wasd keys with the mouse.
