functional - about the game
functional challenges players with math puzzles centered on abstraction. Begin with basic mathematical primitives where every element acts as a function. Build solutions from the ground up, then reuse them as modular components to tackle tougher challenges. Craft intricate logic by treating prior solutions like black boxes. Compare your work against other players and Steam friends for efficiency and simplicity. Workshop tools let you design and share custom levels, appealing to simulation fans who enjoy iterative problem-solving and community-driven math logic.
