Portal 2Where's My Water? 2
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.
Where's My Water? 2
Finger-drawn dirt cuts need only mild precision
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.
Where's My Water? 2
Solo physics puzzles - no opponent
Variance0 vs 1
Where's My Water? 2 leans a little harder on variance, though the gap is small.
Portal 2
Puzzles are deterministic with no randomness.
Where's My Water? 2
Levels are fixed and fully visible
Optimization9 vs 6
Portal 2 leans clearly harder on optimization.
Portal 2
Solving the puzzle's logic IS the entire game.
Where's My Water? 2
Each level has solvable optimal cut sequences
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.
