Portal 2vsThe Swapper
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Portal 2
Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
The Swapper
Optimization · Pure Optimization
Atmospheric sci-fi puzzler about swapping consciousness between your own clones.
Portal 2 leans Optimization (Pure Optimization); The Swapper leans Optimization (Pure Optimization).

Axis by axis
Execution3 vs 2
Portal 2 leans a little harder on execution, though the gap is small.
Portal 2
Portal placement requires some precision but timing is lenient.
The Swapper
Light platforming; precision rarely gates progress
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
No opponent; puzzles are static.
The Swapper
No opponent exists
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Portal 2
Puzzles are deterministic with no randomness.
The Swapper
Deterministic rooms with no hidden state
Optimization9 vs 8
Portal 2 leans a little harder on optimization, though the gap is small.
Portal 2
Solving the puzzle's logic IS the entire game.
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.
