I assume that it's freely posting the mp3 and wav files that is/was the issue, correct. Nothing to stop him from doing what he's doing. Nothing to stop him from posting about his process, his progress, talking about what he does, etc. I would think he could even do youtube videos of the sounds in-game, etc. It's the providing these on the download site and linking from his dropbox (the distrubution) that was the issue.
I hope you'll keep going. Don't have this title, but enjoy seeing these projects very much!
