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.

Execution · Light / Casual
Wordless watercolor platformer about grief, designed never to punish you.

Optimization · Light / Casual
A surreal British comedy game where a tiny salesman slaps his way through a Yorkshire town's errands.
Gris leans Execution (Light / Casual); Thank Goodness You're Here! leans Optimization (Light / Casual).
Gris leans a little harder on execution, though the gap is small.
Gris
Gentle platforming with no fail state
Thank Goodness You're Here!
Walking and slapping, nothing demanding
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gris
No opposition at all
Thank Goodness You're Here!
No opponent, only townsfolk bits
Gris leans a little harder on variance, though the gap is small.
Gris
Linear and fully authored
Thank Goodness You're Here!
Jokes land in fixed order
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gris
Light environmental puzzles with obvious solutions
Thank Goodness You're Here!
Light errand sequencing at most
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.
