head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is optimization, and it is a single point.

Optimization · Pure Optimization
Hand-drawn puzzle where overlapping illustrated panels unlock impossible connections.

Optimization · Pure Optimization
Untangling surreal fixed puzzle chains room by macabre room.
Gorogoa leans Optimization (Pure Optimization); Rusty Lake Hotel leans Optimization (Pure Optimization).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Gorogoa
Dragging panels requires no 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.
Gorogoa
No opponent exists
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.
Gorogoa
Solutions unknown on first encounter only
Rusty Lake Hotel
Solutions are hidden until discovered, then fixed
Gorogoa leans a little harder on optimization, though the gap is small.
Gorogoa
Each panel arrangement has one elegant solvable answer
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.
