This structural randomization means you can never rely on static walkthroughs or muscle memory. Instead, you have to adapt your exploration route dynamically based on what you find. Compounding this challenge is the strict one-item inventory limit. Because you can only carry a single tool at a time, granny 1 forces you into high-stakes decision-making. You must constantly weigh the risk of leaving a critical tool behind versus backtracking through heavily patrolled hallways to retrieve it later.
