Tiny Glade 'built' its way to >600k sold in a month

The seamless integration between one type of object and another is really impressive. The way that the blocks in the roofline perfectly work regardless of the height of the roof is a great example.

How is this possible? Is it some kind of procedural geometry that fills in the available space?

It is surely procedural, maybe wave function collapse? I’d love to read a writeup from the author, in the same style of Factorio’s

The texture is certainly procedural for brick patterns, etc. but I'll bet smoothing intersecting polys happens at render time.
