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

Optimization · Pure Optimization
A pure deduction puzzle with a single solvable answer set.
Baba Is You leans Optimization (Pure Optimization); Return of the Obra Dinn 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.
Baba Is You
No reflex or input precision involved.
Return of the Obra Dinn
No mechanical execution required
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.
Return of the Obra Dinn
Static scenes, no opponent
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.
Return of the Obra Dinn
Fully deterministic puzzle
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.
Return of the Obra Dinn
Pure deductive logic on a fixed manifest
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.
