How Long Is Planet of Lana II: Children of the Leaf?
You sit down for a quick chapter, miss one stealth read, and suddenly the night is gone. That is the rhythm of Planet of Lana II: Children of the Leaf. For most players, a main-story run lands around 6 to 8 hours if you mostly follow the story and do not stop for every secret.
If you play slowly, poke into side paths, and start hunting for hidden holograms, that clock climbs fast. One early review came in at about 7 hours while still missing some secrets, and another put the trip close to 8 hours. So yes, a careful run can stretch past the short end pretty easily. This is still a focused cinematic puzzle-platformer, not a giant map game, but missed routes, repeated stealth rooms, and extra secret hunting all add up.
If you want to stay near the low end, do not brute-force the parts that stall you out. Reset the room and read it in order: what Lana can do, what Mui can do, and what changes when you use both together. In stealth, watch one full patrol loop before you move. That tiny reset saves a surprising amount of time and gets your rhythm back fast.
