head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Optimization · Pure Optimization
Puzzle sequel where glove powers paint blocks to solve physical room logic.

Optimization · Pure Optimization
Atmospheric sci-fi puzzler about swapping consciousness between your own clones.
Q.U.B.E. 2 leans Optimization (Pure Optimization); The Swapper 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.
Q.U.B.E. 2
Occasional timing on moving blocks only
The Swapper
Light platforming; precision rarely gates progress
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Q.U.B.E. 2
No adaptive element exists
The Swapper
No opponent exists
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Q.U.B.E. 2
Deterministic puzzles with full information
The Swapper
Deterministic rooms with no hidden state
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Q.U.B.E. 2
Glove-power combinations resolve to clean solutions
The Swapper
Clone-placement puzzles have fixed solvable solutions
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.
