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

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

Optimization · Pure Optimization
Board-game distillation of Hitman into elegant fully-solvable turn puzzles.
Baba Is You leans Optimization (Pure Optimization); Hitman Go 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.
Hitman Go
Turn-based taps, zero dexterity
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.
Hitman Go
Enemy pieces move on fixed deterministic rules
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.
Hitman Go
All information visible on the board
Baba Is You leans a little harder on optimization, though the gap is small.
Baba Is You
Literally solvable — find the rule rewrite that wins.
Hitman Go
Each diorama is a literally solvable movement puzzle
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.
