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 tactile toy-box puzzler testing playful experimentation with hidden mechanisms.

Optimization · Pure Optimization
Untangling surreal fixed puzzle chains room by macabre room.
Gnog leans Optimization (Pure Optimization); Rusty Lake Hotel leans Optimization (Pure Optimization).
Gnog leans a little harder on execution, though the gap is small.
Gnog
Poking and spinning toy heads requires no dexterity
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.
Gnog
The toys are charming clockwork, not minds
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.
Gnog
Each head's mechanisms are unknown until fiddled with
Rusty Lake Hotel
Solutions are hidden until discovered, then fixed
Rusty Lake Hotel leans a little harder on optimization, though the gap is small.
Gnog
Discovering each contraption's interaction sequence is the puzzle
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.
