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
Zen sliding-droplet puzzler about clearing pearls in the fewest moves.
Baba Is You leans Optimization (Pure Optimization); Quell leans Optimization (Pure Optimization).
Quell leans a little harder on execution, though the gap is small.
Baba Is You
No reflex or input precision involved.
Quell
Swipes only; no timing pressure
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.
Quell
No opponent exists
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.
Quell
Fully deterministic boards
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.
Quell
Minimum-move sliding solutions are pure logic
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.
