It's got all the essential elements of Factorio that make it so interesting and compelling, which apply to so many other fields from VLSI design to networking to cloud computing.
But you mine shapes and colors and combine them into progressively more complex patterns!
What Factorio started, grew up into entire genre. Various ideas are vigorously explored by various games.
