Unity can do the job do not worry ! Have you used the already 'built-in' physics2d functions? Take pieces of code from tutorials can help progress really fast. Using Godot on my side, cannot help you in more details here :)
Yes I did use built in Unity physics. In fact project is 3D, but I switched to isometric camera view just because it looked a lot better)
Oh yes true, Unity is always 3d which can make it a bit difficult when only using 2d!
