Issue with Batch file input for "War Games" game - batch-file

Question

If you are familiar with the 1983 movie "War Games" you should remember the part where the computer ask him "Shall We Play a Game". I have been trying to recreate that and this is what I have so far. The issue is after I enter the password the Command Prompt window closes out. Can someone help me find my mistake?
#echo off
title Shall We Play a Game?
color 0b
set /a tries=3
set password=Joshua
:top
echo %tries% Tries Remaining
set /p pass=Password:
if %pass%==%password% (
goto correct
)
set /a tries=%tries -1
if %tries%==0 (
goto penalty
)
cls
goto top
:penalty
echo CONNECTION TERMINATED
pause
exit
:correct
goto greeting
:greeting
echo Shall we play a game?
echo y/n
set input=
if %input%=y goto y
if %input%=n goto n
:y
echo How about
echo Chess
echo Tic-Tac-Toe
echo Snake
echo Global Thermonuclear War
if %opt%==Chess goto Chess
if %opt%==Tic-Tac-Toe goto TicTacToe
if %opt%==Snake goto Snake
if %opt%==Global Thermonuclear War goto Global Thermonuclear War
:n
echo Thats too bad! Maybe we should play some other day!
pause
exit
:chess
:tictactoe
echo Are you sure?
echo y/n
set response=
if %response%==y goto tictactoe1
if %response%==n goto tictactoe2
:tictactoe1
echo Go Back?
echo y/n
set feedback=
if %feedback%==y goto greeting
if %feedback%==n goto tictactoe2
:tictactoe2
echo testing
goto tictactoe2

This should be what you're trying to do:
#echo off
title Shall We Play a Game?
color 0b
set /a "tries=3"
set "password=Joshua"
:top
echo %tries% Tries Remaining
set /p "pass=Password: "
if "%pass%"=="%password%" (
goto correct
)
set /a "tries=%tries% -1"
if %tries%==0 (
goto penalty
)
cls
goto top
:penalty
echo CONNECTION TERMINATED
pause
exit
:correct
goto greeting
:greeting
echo Shall we play a game?
echo y/n
set /p "input="
if "%input%"=="y" goto y
if "%input%"=="n" goto n
:y
echo How about
echo Chess
echo Tic-Tac-Toe
echo Snake
echo Global Thermonuclear War
set /P "opt="
if "%opt%"=="Chess" goto Chess
if "%opt%"=="Tic-Tac-Toe" goto TicTacToe
if "%opt%"=="Snake" goto Snake
if "%opt%"=="Global Thermonuclear War" goto GlobalThermonuclearWar
:n
echo Thats too bad! Maybe we should play some other day!
pause
exit
:chess
:tictactoe
echo Are you sure?
echo y/n
set /p response=
if %response%==y goto tictactoe1
if %response%==n goto tictactoe2
:tictactoe1
echo Go Back?
echo y/n
set /p feedback=
if %feedback%==y goto greeting
if %feedback%==n goto tictactoe2
:tictactoe2
echo testing
goto tictactoe2
You forgot /P in a set a couple of times, this is used to get user input. In your set /a tries=%tries -1 you also forgot to put a second % around tries, this should be set /a tries=%tries% -1. Furthermore, you should put "" double quotes around your variables if you're comparing them, this prevents the script from braking if a variable doesn't exist or is empty. You also shouldn't have spaces in your labels, and you should put quotes around your set, like this: set "variable=value", this prevents trailing spaces from getting in your variables
