You have to watch out; monsters are dangerous, and they are not all identical. Bomb Monster: When you kill it, it will explode and damage other surrounding monsters. Prism Crystal: Any object goes through it will be duplicated, but the status of the duplicate is not stable. Elite Monster: They are enormous, and will split into two smaller ones when killed. Chaos Monster: When you attack it, it will swallow your ball. Now, swipe and shoot the balls to the monsters!
