I think that the best way of doing it, and always avoiding big images, is to use a pack of 4 or 6 small different sprites and replicate them to shape the world and then using tilemap for all the decorations. The only problem of this, would be the amount of images overlapping each other and object count that would reach almost 90. Anyone would recommend differently?
With tilemap would be really hard to achieve these smooth curves and also really confusing to create, so using it only for the decorations would be my choice.
In this image I'm pointing some examples that makes the scenario, so Ignore all the decorations.
I hope you understand my idea
Any idea to achieve it and have the same performance potential of a tilemap?
I'm focusing on mobile so it's important
