Sound beep game

Guess the sound being played by the game. The sound is a frequency between 400 and 900 hz, and is representative of a number between 1 and 100. Your objective is to guess the appropriate number based off of the tone you hear. Unfortunately, due to not knowing how to make a beep on any platform but windows, this program will only work on windows for now. Anyone who knows how to make this program work on any other platform, please contact me or file a bug and I can try to fix it. If you do, please tweet or email me so I make sure to see your bug.
