head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

A non-Euclidean exploration puzzle testing your willingness to abandon assumptions about space.

Zen sliding-droplet puzzler about clearing pearls in the fewest moves.
Antichamber leans Optimization (Pure Optimization); Quell 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.
Antichamber
Navigation has no twitch demands
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.
Antichamber
No opponent; solo non-Euclidean exploration
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.
Antichamber
World is deterministic once its rules are understood
Quell
Fully deterministic boards
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Antichamber
Deducing the non-Euclidean spatial logic and gun mechanics governing each room
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.
