Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby Super Star
Helper juggling and The Arena demand competence
Lumo
Isometric jumps with tricky perspective punish imprecision
Same score on reads - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby Super Star
Pattern-based bosses throughout
Lumo
Rooms are fixed challenges with no opponent
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby Super Star
Treasure locations in Great Cave are fixed
Lumo

Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Kirby Super Star
