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 · Practiced Mastery
Slapstick physics puzzler about hauling a wobbly ragdoll through dreamscapes.

Optimization · Practiced Mastery
A four-player Wii Kirby romp gathering ship parts for the stranded alien Magolor.
Human: Fall Flat leans Optimization (Practiced Mastery); Kirby's Return to Dream Land leans Optimization (Practiced Mastery).
Human: Fall Flat leans a little harder on execution, though the gap is small.
Human: Fall Flat
Wrestling floppy physics limbs is the joke
Kirby's Return to Dream Land
Easygoing main game; EX mode adds modest demands
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Human: Fall Flat
No adversary, only wobbly geometry
Kirby's Return to Dream Land
Bosses are pattern-scripted
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Human: Fall Flat
Physics jank adds slapstick unpredictability
Kirby's Return to Dream Land
Energy sphere hiding spots are static secrets
Human: Fall Flat leans a little harder on optimization, though the gap is small.
Human: Fall Flat
Puzzle solutions and shortcut discovery
Kirby's Return to Dream Land
Super ability timing and sphere collection are solvable
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.
