I would like a top down view
that's not topdown
topdown looks like that:
example from Hotline MiamiWhat you currently have there is an orthogonal axonometric projection with a viewing angle of 45°
The more handy term usually used for that kind of graphical representation is "RPG-projection" (because it was established and used by most of the classic early RPGs)
the difference between perspective and projection are the vanishing points.
For any projection the vanishing point(s) is approximating infinity, which means that the consequence is that all the axis are parallel.
Although since we are operating in a 2D space, rather than in a 3D space, we can deliberately break rules to enhance the form, like you did with the counter top of the shop.
