Nyan Cat Comet Frenzy! (FONT/MUSIC/GIF)

//vBUGSv//

// 1. GETTING THE SOUND TO WORK

// I cannot seem to get the sound to work in openprocessing, it works fine before converted for the site.

// 2. GIFS 

// Gifs also do not work in openprocessing.

// Conclusion: I have created two working files, one for openprocessing, and one for hand-in.
