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 · Pure Optimization
LucasArts adventure sending Indy down three routes toward Atlantis.

Optimization · Pure Optimization
A musical adventure where learning and reversing melodic spells forms a closed combinatorial puzzle system.
Indiana Jones and the Fate of Atlantis leans Optimization (Pure Optimization); Loom leans Optimization (Pure Optimization).
Loom leans a little harder on execution, though the gap is small.
Indiana Jones and the Fate of Atlantis
Pointing and clicking, light fistfight option
Loom
Musical spell sequences require accurate note input under light pressure
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Indiana Jones and the Fate of Atlantis
No adaptive opposition
Loom
Fantasy narrative with scripted antagonists
Indiana Jones and the Fate of Atlantis leans a little harder on variance, though the gap is small.
Indiana Jones and the Fate of Atlantis
Solutions hidden until reasoned out
Loom
Deterministic world with no randomised elements
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Indiana Jones and the Fate of Atlantis
Three-path puzzle chains reward deduction
Loom
Learning and combining distaff spells in the correct order is a fully solvable logic system
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.
