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.

Optimization · Pure Optimization
Sequel that adds a mother-daughter pair to its impossible-architecture puzzles.

Optimization · Pure Optimization
Idle shooter where automated guns and well-timed prestige resets dissolve cube fortresses.
Monument Valley 2 leans Optimization (Pure Optimization); Time Clickers leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Monument Valley 2
Gentle touch controls, no reflexes
Time Clickers
Manual clicking helps early, then automates
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Monument Valley 2
Nothing opposes you
Time Clickers
Targets are inert cubes
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Monument Valley 2
Deterministic authored levels
Time Clickers
Negligible randomness
Time Clickers leans a little harder on optimization, though the gap is small.
Monument Valley 2
Geometry manipulation puzzles with intended solutions
Time Clickers
Weapon upgrades and time-warp resets drive everything
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.
