The demo is very, very close to release. All the tiles have been laid out and the level events have been coded. It's just a matter of doing some final bug testing and a bit of fine tuning.
We're primarily focusing on the Windows version right now. After it's out, we will get started on the OUYA version. However, we won't be putting it out on the OUYA market, so you will have to download and sideload the .apk file from us.
After the Windows & OUYA versions are out, we'll start looking at bringing Eclipse onto other platforms (Ubuntu and HTML5 are at the top of that list).
