head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.

Optimization · Pure Optimization
A rule-rewriting puzzle game that is pure deterministic problem solving.

Optimization · Pure Optimization
A visual programming puzzle that teaches algorithmic thinking through factory-floor instruction sequences.
Baba Is You leans Optimization (Pure Optimization); Human Resource Machine leans Optimization (Pure Optimization).
Human Resource Machine leans a little harder on execution, though the gap is small.
Baba Is You
No reflex or input precision involved.
Human Resource Machine
Dragging instructions has no timing component
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Baba Is You
No opponent; puzzles are static.
Human Resource Machine
No opponent; purely computational puzzle
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Baba Is You
Puzzles fully deterministic with no hidden information.
Human Resource Machine
Input data is fixed per level with no randomness
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Baba Is You
Literally solvable — find the rule rewrite that wins.
Human Resource Machine
Writing minimal correct assembly-like programs to pass each input sequence
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.
