I knew that there was a Duo being made for the cellphones in Java (I think), how hard would that be to put 5 levels into a web embedded game...
Funnily enough we were just discussing this on the dev boards a few days ago.
I think SiN would prefer to use Flash for a web version as it would look better but the way I see it we will already have a Java version, so uploading a restricted demo of that version would make sense. Chances are it will be a Java version of nothing.
As we've mentioned before, we have loads of other versions we'd love to write (DS, PSP etc) but with just myself doing the PC coding and SiN doing the mobile versions we simply don't have the resources.....and that's without the additional media they may require.
Anyhoo we like the idea of web versions of some kind so we'll see what we can do
