Question

I am making a game, where enemies from an array move downward at random. In the game there is a menu button. When clicked a different screen pops up. I stopped the enemies movement, so they're at a pause of where they are at currently when the menu button is clicked. The problem I am facing right now is that I can't seem to hide the enemies from the menu screen. I tried using the .visible = false; perimeter, but it only hid one of the enemies instead of all! Could you please help me out with this, thanks!
