Let us know what commit on master you want to use as a baseline for an initial review.

World.java --> setNeighbors
Offsets are always going to be the same for square block systems (unless you're planning for a hexagonal system or similar) . Maybe it should be a static final variable ? I know that you are just calling that method in the constructor iteration. But, each iteration will create a new array.
I am looking forward to run your code on my machine and see it in action !! Will update you soon.

No parameter validation.

Let me give you a hint though. Consider this code and what the JavaDocs declares it does:
How is someone supposed to see how a Cell method is being called on each cell here? Where is the reference to the Cell whose method is invoked? Where is the reference to the method being called? If you can't tell me where those are in this snippet of code, then that means this code is blatantly displaying an inappropriate intimate knowledge of implementation details that are elsewhere in the code.
Junilu Lacar wrote:Names like WorldConsumer and CellConsumer are smelly.
Why not Consumer<World> or Consumer<Cell> instead?
See the difference?

In Demo.java, we see
I have already expressed my objection to this code before but let me reiterate: The semantics of the lambda is unclear. It smells of inappropriate knowledge of intimate details of the implementation of World. I get the first two parameters, they define the boundaries of the new World object. But WTH is this lambda expression trying to say? It looks like it is returning a new ClassicCell() instance but what's with the (x, y) parameters? And why aren't they even used? This is a red flag to me that the design is not coherent. There should be no elements in the design that are not used.

What's the definition of smelly in the context of code?
