What about publishing a self-contained project? If you want to publish your game to other people then maybe you shouldn’t require manually installing something else first. Don’t know what is common to do on Linux though.
Only problem is when I execute the program I get a black window. I think it’s because of an error I also got when using mono on the dll “IsolatedStorageException: No ApplicationIdentity available for AppDomain”
Edit: Maybe this error is because I use IsolatedStorageFile.GetUserStoreForApplication() for saving and loading options, which might not be cross platform.
