Step into the pixelated shoes of Gwen, a gritty Java programmer who stumbles into a cybernetic world where every type has a voice, and null pointers cause chaotic events. Your main mission? Restore order to a corrupted codebase where types have become sentient and are fighting for their existence. As you navigate through each module, every decision you make leads to different interactions between types that either enforce or reject nulls. Solving problems requires you to decide how to handle each type's expectations of nullity, leading to unexpected alliances and dangerous enemies. Uncover the secrets behind the Nullness Markers, which hold the key to saving or condemning this digital universe.
