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 · Pure Mechanics
A tilt-controlled physics game testing motion precision to navigate a duck.

Execution · Pure Mechanics
A classic beat-em-up demanding execution against scripted enemy waves.
Super Rub 'a' Dub leans Execution (Pure Mechanics); Teenage Mutant Ninja Turtles III: The Manhattan Project leans Execution (Pure Mechanics).
Teenage Mutant Ninja Turtles III: The Manhattan Project leans a little harder on execution, though the gap is small.
Super Rub 'a' Dub
Tilt control precision to steer the duck is core
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.
Super Rub 'a' Dub
No opponent to predict
Teenage Mutant Ninja Turtles III: The Manhattan Project
enemies run simple fixed scripts
Super Rub 'a' Dub leans a little harder on variance, though the gap is small.
Super Rub 'a' Dub
Hazard placement fixed per tub
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.
Super Rub 'a' Dub
Fast routes through tubs reward planning
Teenage Mutant Ninja Turtles III: The Manhattan Project
character choice and route memorization
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.
