The core gameplay of the game is for players to choose prosthetics and defeat other enemies, which not only tests their ability and timing to control the rolling of fat ball animals, but also requires players to combine appropriate prosthetic combinations to defeat opponents. Players can choose different prosthetics to fit on their characters, and they can control the character to roll and hit the enemy at the appropriate angle and timing, causing damage until the enemy's health reaches zero. Different prosthetics have different effects and abilities, including the legs of street fighters sweeping their heads, and the fists of combat masters, which have different effects and injuries. By combining and arranging appropriately, one can effectively and quickly defeat the enemy to win victory.
