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

Optimization · Practiced Mastery
Working out scripted environmental puzzles with light platforming in a narrative world.

Optimization · Practiced Mastery
A minimalist puzzle platformer about cooperating rectangles, carried by warm narration.
Papo & Yo leans Optimization (Practiced Mastery); Thomas Was Alone leans Optimization (Practiced Mastery).
Thomas Was Alone leans a little harder on execution, though the gap is small.
Papo & Yo
Light platforming jumps with forgiving timing
Thomas Was Alone
Light precision jumps per quadrilateral
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Papo & Yo
Monster's frenzy follows fixed trigger rules, not a mind
Thomas Was Alone
No opponent, narrated rectangles
Papo & Yo leans a little harder on variance, though the gap is small.
Papo & Yo
Puzzles are fully scripted, nothing random
Thomas Was Alone
Levels fully visible and fixed
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Papo & Yo
Each environmental puzzle has one discoverable solution
Thomas Was Alone
Sequencing each character's ability per puzzle
