The problem of a bug in the new version of the demo forced me to take it down until I fixed the problem.
The problem has been fixed and the download is available again for version 2 of the demo.
Version 2 has been improved, corrected and added bunnies and a level, and other things.
As specified here:

You can find the download on the main page, as usual.
