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

Execution · Pure Mechanics
A gravity-manipulation action game that lives or dies on aerial movement mastery.

Execution · Pure Mechanics
A classic beat-em-up demanding execution against scripted enemy waves.

Teenage Mutant Ninja Turtles III: The Manhattan Project leans a little harder on execution, though the gap is small.
Gravity Rush Remastered
gravity-shift platforming and aerial combat control
Teenage Mutant Ninja Turtles III: The Manhattan Project
beat-em-up timing and enemy juggling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gravity Rush Remastered
no adaptive opponents, all scripted foes
Teenage Mutant Ninja Turtles III: The Manhattan Project
enemies run simple fixed scripts
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gravity Rush Remastered
minor enemy spawn randomness
Teenage Mutant Ninja Turtles III: The Manhattan Project
minor enemy spawn randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Gravity Rush Remastered
upgrade tree and mission routing
Teenage Mutant Ninja Turtles III: The Manhattan Project
character choice and route memorization
