Again, I am making a game but yet I ran into another problem. I have a set of actions a player can do, until they run out of energy. The problem I have is this: When they choose an action, it prompts for another action. Yet, when they type anything into the prompt, it closes itself. I know one solution: Copy and paste the code and basically make the code 6x larger by repeating code. But I wanna know if it's possible to: How can I make it so I can rollback a case in a switch-statement to repeat itself, but keep the current stats? Here's my JavaScript (currently not finished)

</html>THINGS TO NOTE
If possible, when the case rolls back to the previous prompt/step, it should keep the current energy/day variable, too. If possible, can it just go back to the previous prompt? If not possible, how can I shorten the code as much as possible to make it meet my requirement?
