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

Optimization · Light / Casual
A gentle social journey testing little beyond exploration and cooperation.

Execution · Light / Casual
A puzzle horror game about learning trap solutions through trial and error.
Sky: Children of the Light leans Optimization (Light / Casual); The Witch's House MV leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Sky: Children of the Light
Gentle flight controls with no failure pressure
The Witch's House MV
occasional quick reactions to avoid death traps
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Sky: Children of the Light
Other players are companions, not adversaries
The Witch's House MV
no adaptive opponent, puzzle-driven horror
The Witch's House MV leans a little harder on variance, though the gap is small.
Sky: Children of the Light
Daily events rotate on known schedules
The Witch's House MV
some trial-and-error trap randomness
Sky: Children of the Light leans a little harder on optimization, though the gap is small.
Sky: Children of the Light
Candle routes and collectible runs are lightly optimisable
The Witch's House MV
learning correct puzzle solutions
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.
