Yeah that's what I wanted to do WarHamster, and I appreciate the help, everyone, but I did a little research, and it seems Processing 2.0 will no longer export to an applet. I would have to convert to Processing.js (which compiles the same code but to JavaScript) which means I couldn't use any of my current libraries. That includes the file i/o since levels are saved as .txt files, and also my sound and music.
I'm actually getting a bit tired of these limitations and if I don't figure it out soon I may switch to something new. Processing is still way useful for experimenting but it kind of feels like using 'training wheels'. If I could even just put the same Java code together without Processing I could probably embed it, but I'm not so sure.
Kind of puts a damper on my enthusiasm for doing more work on the game.
