Intro: G5 B5 G5 F5 F5

G5
I'm kind of ordinary
B5
To me you were sort of scary
G5           
But you seemed to like me
D5                         D5                         
And that don't happen that much


G5
So I threw caution to the wind
B5
Gave you one half-hearted grin
G5
That's all that it took
D5                  D5                  
For you to try your luck
A5                        G5
How was I to know you run hot and cold
A5                    F5    F5   
That you'd get inside my mind

CHORUS
G5
Level 1 you played me
B5
2, you paused me
G5   F5    F5    
3, I realized
G5
Your high score show
B5     
Your cheats don't work
G5               F5     
Your 3 lives up, bad luck
     F5
Now, it's game over!

Samo as intro:
G5 B5 G5 F5 F5 

G5
This is how its gonna be
B5
That's what you chose to be believe
G5          
Made me stay in while
D5                            D5 
You were out with all your friends
G5
I was advised to walk away
B5
But you blinded me enough to stay
G5
I'm through with all your all your lies
D5                   D5 
And this is where it ends
A5                      G5      
Yeah you played to win, I was taken in
A5                     F5  F5  
But now you are out of time

CHORUS
G5
Level 1 you played me

     F5
Now, it's game over!

I'm sorry but i couldn't figure out this part.
               
No repeat chance, you blew it
              
You get no more clues
                                 
Now you're all out of special moves
            
Too bad you lose

CHORUS
