We need to use the blade around the character to solve the monsters that appear in the level. Sometimes the new blade will be dropped during the killing process, and we will kill some monsters and there will be game props. These monsters can't be touched by the characters inside. The characters inside have no attacking power and can only be attacked by the blade.
This game is mainly based on the defensive, if the monster is too much to draw, the blade can be used without a knack, but the props still try to get it. The kind of blood is especially easy to destroy the enemy, and the play is also quite decompressing.
