Bubu Chuǎng Tōng Guān

Progressing through every stage leads to a boss encounter before advancing to the next world. Players guide the octopus through maze-like stages, placing small black octopi that function as bombs. Their explosions defeat enemies, destroy breakable rocks, and uncover hidden items. The key required to complete each stage is concealed beneath destructible terrain. After finding it, a skull marker appears elsewhere in the level; destroying it reveals the exit door. The game is divided into themed worlds, each ending with a boss battle.
