I tried downloading the Linux app and all it downloaded was a short script telling the computer how to run the source code. But I downloaded the mac package and found the Java folder, renamed it to "lib" like the first script said. And "Gamefont.ttf" is in the data folder so I had to move it to a folder with the lib folder and the shell script. And after all that, it worked! It was a fun to play but I think Processing's Linux packager is broken.
