Batch File 'if " "goto " " Not working

I was creating a batch game, and I had a previous game I made so I could remember stuff from the code.

On the game I was working on the If and Goto command where not working. So I testing my previous game, and it worked fine with things like that. So I created This:

@echo off   
title test
:1
cls
echo testing Testing 123
echo Type Go
set /p 123=
if %123% == Go goto 2
if %123% == go goto 2
:3
echo Gone wrong :(
pause
exit
:2
cls
echo Worked
pause
exit

And When I type Go It says Gone Wrong :(

Can anyone help me with this?
