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

Optimization · Pure Optimization
Dreamlike island Zelda built on dungeon puzzles and a long trading chain.

Optimization · Pure Optimization
A scripted RPG where pattern-learning and pacifist routing carry you.
The Legend of Zelda: Link's Awakening leans Optimization (Pure Optimization); Undertale 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.
The Legend of Zelda: Link's Awakening
Top-down combat with light platforming segments
Undertale
Bullet-hell dodging in scripted patterns
Undertale leans a little harder on reads, though the gap is small.
The Legend of Zelda: Link's Awakening
Scripted enemies and bosses
Undertale
NPCs follow fixed dialogue trees, not adaptive
The Legend of Zelda: Link's Awakening leans a little harder on variance, though the gap is small.
The Legend of Zelda: Link's Awakening
Trading-sequence and secret discovery on first run
Undertale
Minimal randomness in encounters
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Legend of Zelda: Link's Awakening
Dungeon puzzles and item interdependencies
Undertale
Learning fixed boss patterns and mercy routes wins
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.
