head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
Using time-rewind to pre-solve grapple and kill sequences against fully deterministic guard patrols.

Optimization · Pure Optimization
Time-loop Zelda where mastering everyone's three-day schedule is the real puzzle.
Shadwen leans Optimization (Pure Optimization); The Legend of Zelda: Majora's Mask leans Optimization (Pure Optimization).
The Legend of Zelda: Majora's Mask leans a little harder on execution, though the gap is small.
Shadwen
Grapple hook timing and kill windows need care but are forgiving
The Legend of Zelda: Majora's Mask
Standard Zelda combat demands
Shadwen leans a little harder on reads, though the gap is small.
Shadwen
Guards follow scripted patrol arcs without profiling player tactics
The Legend of Zelda: Majora's Mask
NPCs run fixed clockwork schedules
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Shadwen
Child NPC pathfinding adds minor unpredictability to routing plans
The Legend of Zelda: Majora's Mask
Schedules hidden until observed, then fully mappable
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Shadwen
Time-rewind and rope construction enable full pre-optimisation of every kill sequence
The Legend of Zelda: Majora's Mask
Three-day time loop rewards ruthless scheduling and routing
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
