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 · Systems & Chaos
Minimalist horror adventure testing patient puzzle work through fixed Victorian dread.

Optimization · Pure Optimization
Lateral-thinking puzzle solving that converges to a walkthrough once solutions are known.
The Last Door leans Optimization (Systems & Chaos); The Secret of Monkey Island: Special Edition leans Optimization (Pure Optimization).
The Last Door leans a little harder on execution, though the gap is small.
The Last Door
Low-res clicking demands nothing physically
The Secret of Monkey Island: Special Edition
Pointing and clicking has no physical ceiling
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
The Last Door
Lovecraftian horrors are scripted scenes, not minds
The Secret of Monkey Island: Special Edition
Insult swordfighting is scripted dialogue lookup, not prediction
The Last Door leans a little harder on variance, though the gap is small.
The Last Door
The cryptic story is hidden information revealed linearly
The Secret of Monkey Island: Special Edition
Puzzle solutions are hidden information until discovered
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
The Last Door
Each chapter's puzzles have one discoverable solution
The Secret of Monkey Island: Special Edition
Once solutions are known the game is fully solved
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.
