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

Execution · Pure Mechanics
A dual-stick coordination game testing split-brain control of two avatars at once.

Execution · Pure Mechanics
A classic beat-em-up demanding execution against scripted enemy waves.
Entwined leans Execution (Pure Mechanics); Teenage Mutant Ninja Turtles III: The Manhattan Project leans Execution (Pure Mechanics).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Entwined
Steering two characters on separate sticks simultaneously is the whole test
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.
Entwined
No opponent - only flowing obstacle lanes
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.
Entwined
Patterns repeat predictably within each lifetime
Teenage Mutant Ninja Turtles III: The Manhattan Project
minor enemy spawn randomness
Teenage Mutant Ninja Turtles III: The Manhattan Project leans a little harder on optimization, though the gap is small.
Entwined
Little to solve beyond reading upcoming gate colours
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.
