About Knife io

Defeated opponents and collected orbs support level growth. That progression remains fragile because a fall sends the player back to square one, giving every aggressive move a clear risk.

Objective: Defeat foes, gather orbs, and level up the twin-blade fighter without falling and losing the accumulated progress.
