Human Resource MachinevsPortal 2
Portal 2 asks more than Human Resource Machine, and the gap is execution.
Human Resource Machine
Optimization · Pure Optimization
A visual programming puzzle that teaches algorithmic thinking through factory-floor instruction sequences.
Portal 2
Optimization · Pure Optimization
A first-person puzzle game where seeing the solution is the whole skill.
Human Resource Machine leans Optimization (Pure Optimization); Portal 2 leans Optimization (Pure Optimization).
Human Resource MachinePortal 2
Axis by axis
Execution1 vs 3
Portal 2 leans clearly harder on execution.
Human Resource Machine
Dragging instructions has no timing component
Portal 2
Portal placement requires some precision but timing is lenient.
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
No opponent; purely computational puzzle
Portal 2
No opponent; puzzles are static.
Variance0 vs 0
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Human Resource Machine
Input data is fixed per level with no randomness
Portal 2
Puzzles are deterministic with no randomness.
Optimization10 vs 9
Human Resource Machine leans a little harder on optimization, though the gap is small.
Human Resource Machine
Writing minimal correct assembly-like programs to pass each input sequence
Portal 2
Solving the puzzle's logic IS the entire game.
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.
