Hi, I suspect that the problem is in draw calls count and you need to reduce it. You can reduce draw call in mobile 2D game by implementing texture atlases (Unity Sprite Editor) for sprites, use mobile friendly shaders, use one material for many objects and also you should use low poly objects and low number of particles. This will help you :)
