head to head
Neither is harder. They score identically on all four axes, so the difference between them is in kind, not degree.

Execution · Light / Casual
A casual licensed action game testing little beyond light co-op coordination.

Execution · Light / Casual
Cheerful physics platformer about a kicking blob toppling a capitalist conspiracy.
Harry Potter and the Goblet of Fire leans Execution (Light / Casual); Pikuniku leans Execution (Light / Casual).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter and the Goblet of Fire
Simple co-op spell casting with generous timing
Pikuniku
Floppy kicks and hops, gently imprecise
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter and the Goblet of Fire
Enemies are fixed waves, no adaptation
Pikuniku
No adversary anywhere
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter and the Goblet of Fire
Collectible bean locations are fixed
Pikuniku
Short authored world with few surprises
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Harry Potter and the Goblet of Fire
Light card collection and spell upgrade choices
Pikuniku
Simple puzzles with obvious solutions
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.
