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

Optimization · Pure Optimization
Charming diorama puzzler about routing a jumpless Toad to each star.

Optimization · Pure Optimization
Using time-rewind to pre-solve grapple and kill sequences against fully deterministic guard patrols.
Captain Toad: Treasure Tracker leans Optimization (Pure Optimization); Shadwen leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Captain Toad: Treasure Tracker
Gentle navigation, no jumping, light timing
Shadwen
Grapple hook timing and kill windows need care but are forgiving
Shadwen leans a little harder on reads, though the gap is small.
Captain Toad: Treasure Tracker
No adaptive opposition anywhere
Shadwen
Guards follow scripted patrol arcs without profiling player tactics
Shadwen leans a little harder on variance, though the gap is small.
Captain Toad: Treasure Tracker
Everything is visible and fixed
Shadwen
Child NPC pathfinding adds minor unpredictability to routing plans
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Captain Toad: Treasure Tracker
Rotating dioramas to solve fixed route puzzles
Shadwen
Time-rewind and rope construction enable full pre-optimisation of every kill sequence
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.
