You mean the fireball, right? No, there can be several on screen at once. The range may appear different because once it hits an enemy the object (fireball) is destroyed. I definitely need to make it better with player feedback so that they know the fireball actually hit the enemies. I think one problem is that the fireball's collider is the size of a square which is too big and doesn't allow for it to make a visual connection with enemies on screen. Thank you for playing my game!
