So I am making a game where you need to shoot enemies before they reach the end of the screen and I want to be able to have a store and have the player be able to access it anytime they want. I made the store a different layout and when the hit 's' the game will change to the store layout. The only problem is when they go back to the game all the monsters disappear. They start spawning again but I want them to stay in their positions when a player goes to the store.
