I've killed the last enemy (boss) in first world by damage from rupture, after that the next world did not unlock. Is it supposed to work like that? Do i need to kill this enemy few mote times?
Update: i've killed it again, this time it either died on its own (it seems to be receiving dmg from unknown source) or i've killed it with normal attack and the next world has been unlocked.

The way the boss dies shouldn't matter at all, the thing that actually unlocks the next progress step is the teleporter after the boss. So if you had died/retreated/closed that would prevent the next world from unlocking.
So unless something really weird happened, I've got no clue why it wouldn't have worked for you.
