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

Execution · Light / Casual
A pack-in 3D platformer celebrating PlayStation history.

Optimization · Practiced Mastery
A 3DS Kirby playing with foreground-background depth and the vacuum-everything Hypernova power.
Astro's Playroom leans Execution (Light / Casual); Kirby: Triple Deluxe leans Optimization (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Astro's Playroom
Very forgiving platforming
Kirby: Triple Deluxe
Easy main game, modest arena challenges
Astro's Playroom leans a little harder on reads, though the gap is small.
Astro's Playroom
Scripted enemies
Kirby: Triple Deluxe
Bosses follow fixed patterns
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Astro's Playroom
Static levels
Kirby: Triple Deluxe
Levels fully deterministic
Kirby: Triple Deluxe leans a little harder on optimization, though the gap is small.
Astro's Playroom
Collectible completion
Kirby: Triple Deluxe
Sun-stone hunting and foreground-background gimmick puzzles
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.
