Sadly, it appears that Goo engine is gone. Their website is no longer functional as of Oct 28 (or earlier).
This is a take on the throbber found on old Netscape browsers. The original throbber can be found here.
This was also my first time using the Goo Engine and Creator.
Since Goo Create's free plan no longer allows the export of scenes and bundles, only the assets are offered here.
