About

Zero One Protocol

Read full description

Switch between 0 and 1 to survive. Solve 50+ logic gate puzzles. Dodge lasers. One wrong form - deleted instantly. Pure skill, zero luck. Set inside a collapsing digital world, Zero One Protocol is a punishing precision puzzle-platformer where your form is the key. As 0 or 1, you interact differently with every switch, gate, and hazard - sharp reflexes, tight timing, and pure logic, all required. Handcrafted by indie students from Indonesia. Made with obsession, not a budget.
