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.

Execution · Practiced Mastery
A maze-chase arcade game testing dodging under a scrolling screen's pressure.

Execution · Practiced Mastery
A pinball-platformer hybrid where flippers fling a mail-delivering beetle across an open island.
Devil World leans Execution (Practiced Mastery); Yoku's Island Express leans Execution (Practiced Mastery).
Devil World leans a little harder on execution, though the gap is small.
Devil World
Dodging demons while the scrolling maze crushes you is twitch
Yoku's Island Express
Pinball flipper timing drives all traversal
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Devil World
Demons chase on simple fixed logic
Yoku's Island Express
Solo, nothing models you
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Devil World
Scroll direction shifts add mild unpredictability
Yoku's Island Express
Ball physics adds small bounce unpredictability
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Devil World
Maze routes and cross timing are learnable patterns
Yoku's Island Express
Learning table layouts and exploration routes
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.
