The digital realm trembles as the first lines of defense activate. In Code Cascade Citadel, you command the fortress that guards the last pure kernel of computation — a place where logic itself becomes your weapon. Waves of rogue bugs descend through the cascading code, and only your mastery of logic gates can hold the corruption at bay.

Every AND, OR, NOT, and XOR gate you construct forms part of an intricate defense network powered by your limited energy reserves. Each gate decays over time, flickering with data degradation before collapsing into luminous fragments. Positioning them strategically — overlapping ranges, balancing costs, and reinforcing vulnerabilities — becomes a thrilling puzzle of precision and foresight.

But even pure logic falters against chaos. Bomb Towers bring raw destruction, clearing corrupted code clusters in radiant bursts. Boss Bugs and Glitch Swarms, however, rewrite the rules of engagement with erratic movement and shielded cores, forcing you to adapt your architecture in real time.

Your citadel isn’t just under attack — it’s alive. Pulsing with neon circuits, layered particle streams, and cascading syntax storms, the battlefield feels like an active codebase under siege. And as the waves escalate, so too does your resolve to debug the system and preserve the digital sanctum.
