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
A cozy hidden-object adventure testing visual search and light puzzle solving.

Optimization · Pure Optimization
Untangling surreal fixed puzzle chains room by macabre room.
Lost and Found Co. leans Optimization (Pure Optimization); Rusty Lake Hotel leans Optimization (Pure Optimization).
Lost and Found Co. leans a little harder on execution, though the gap is small.
Lost and Found Co.
Clicking objects, no twitch skill
Rusty Lake Hotel
Pointing and clicking - no dexterity involved
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Lost and Found Co.
Solo, no adaptive opponent
Rusty Lake Hotel
No opponents, only macabre puzzle rooms
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Lost and Found Co.
Item locations hidden until searched
Rusty Lake Hotel
Solutions are hidden until discovered, then fixed
Rusty Lake Hotel leans a little harder on optimization, though the gap is small.
Lost and Found Co.
Systematic searching and puzzle-solving is the loop
Rusty Lake Hotel
Chaining surreal puzzle logic per room is the whole 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.
