FactoriovsLorelei and the Laser Eyes
Neither is meaningfully harder - they pose close to the same test. The widest gap is execution, and it is a single point.
Factorio
Optimization · Pure Optimization
A factory-engineering sandbox about scaling throughput against your own bottlenecks.
Lorelei and the Laser Eyes
Optimization · Pure Optimization
An austere puzzle labyrinth where every room presents a closed logical system that must be fully solved.
Factorio leans Optimization (Pure Optimization); Lorelei and the Laser Eyes leans Optimization (Pure Optimization).
FactorioLorelei and the Laser Eyes
Axis by axis
Execution2 vs 1
Factorio leans a little harder on execution, though the gap is small.
Factorio
Some APM in early hand-crafting; otherwise irrelevant.
Lorelei and the Laser Eyes
Minimal motor demand; all puzzles are cognitive
Reads0 vs 0
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Factorio
Biters follow fixed pollution rules; no adaptive opponent.
Lorelei and the Laser Eyes
Surreal manor setting has no adaptive opponent
Variance1 vs 2
Lorelei and the Laser Eyes leans a little harder on variance, though the gap is small.
Factorio
Resource patch placement adds minor map randomness.
Lorelei and the Laser Eyes
Some hidden room states and obscured clues require discovery
Optimization10 vs 10
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Factorio
Throughput, ratios, and logistics are the entire game.
Lorelei and the Laser Eyes
Every puzzle is a precisely designed closed logic problem with exactly one valid solution
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.
