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

Optimization · Pure Optimization
Noir stealth puzzler about rewiring buildings so guards defeat themselves.

Optimization · Pure Optimization
Puzzle sequel where glove powers paint blocks to solve physical room logic.
Gunpoint leans Optimization (Pure Optimization); Q.U.B.E. 2 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.
Gunpoint
Jump timing matters occasionally, lightly
Q.U.B.E. 2
Occasional timing on moving blocks only
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Gunpoint
Guards patrol on fixed scripts
Q.U.B.E. 2
No adaptive element exists
Gunpoint leans a little harder on variance, though the gap is small.
Gunpoint
Levels fully visible and deterministic
Q.U.B.E. 2
Deterministic puzzles with full information
Q.U.B.E. 2 leans a little harder on optimization, though the gap is small.
Gunpoint
Crosslink rewiring puzzles have clean optimal solutions
Q.U.B.E. 2
Glove-power combinations resolve to clean solutions
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.
