Hi
Grid graphs on the XY plane is no problem. Just rotate the graph (there is a rotation field in the inspector).
2D physics is also fully supported (just a toggle in the inspector).
It’s the movement scripts for moving along the generated paths that are not fully supported yet (though if you search, there are a couple of 2D scripts I have posted on the forum (see Simple example script for a 2d top down character (y up axis)?) which can be used).
