Thanks for your input. On the matter of artwork being stolen on some level I am prepared for that in any case, as I know how easy it is to decompile a game and access the artwork. In this game the game is written with JavaScript / HTML5 and the artwork will be even easier to steal in production... As for why open source, I thought it would be interesting for others to be able to browse and learn from the source code. Perhaps even contribute changes -- though that's likely a pipedream. Maintaining a separate open repository with separate assets may be the way to go, but means more work for me.
