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.

Optimization · Pure Optimization
A classic arcade game about computing the trajectory to land in a bucket.

Optimization · Pure Optimization
Sitcom puzzle game about rigging perfect prank chains around a fixed routine.
Human Cannonball leans Optimization (Pure Optimization); Neighbours from Hell leans Optimization (Pure Optimization).
Human Cannonball leans a little harder on execution, though the gap is small.
Human Cannonball
Firing requires no real motor precision
Neighbours from Hell
Timing pranks between patrol windows
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human Cannonball
No opponent to model in this arcade game
Neighbours from Hell
The neighbour loops a fixed routine
Human Cannonball leans a little harder on variance, though the gap is small.
Human Cannonball
Some variations randomize the target distance
Neighbours from Hell
Routine unknown on first attempt, then converges
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Human Cannonball
Calculating angle, speed and position is the whole puzzle
Neighbours from Hell
Sequencing pranks for maximum combo rating
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.
