Enhancements to Number of Guess

I have a Guess the Number game where I would like to enhance the game a little more by adding when the user is getting warmer, or colder or if they are freezing or boiling... I have no idea how to do this. I have the game to where it is telling you that the user needs to go higher or lower. Can someone please help me??

And also I want a text box to be able to tell how many guesses they have guessed... how do you do that?

Thanks a million!! :)
