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
Noir stealth puzzler about rewiring buildings so guards defeat themselves.

Optimization · Pure Optimization
Tests creative vocabulary - conjuring the right modified object for each fixed puzzle.
Gunpoint leans Optimization (Pure Optimization); Super Scribblenauts 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
Super Scribblenauts
Stylus control matters slightly, never decisively
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
Super Scribblenauts
Solo sandbox - nothing models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Gunpoint
Levels fully visible and deterministic
Super Scribblenauts
Puzzles are fixed; your vocabulary is the only variable
Gunpoint leans a little harder on optimization, though the gap is small.
Gunpoint
Crosslink rewiring puzzles have clean optimal solutions
Super Scribblenauts
Finding object-adjective combos that satisfy each puzzle is the game
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.
