Vectorpark
In addition to Metamorphabet and Windosill, I've re-packaged selected Flash projects from Vectorpark.com as Windows/MacOS downloadables. I may add more. They're free, but if you'd like to leave a tip it will help enable future projects.
There are also iOS versions of some games, a version of Metamorphabet for Android, and a version of Windosill for the Nintendo Switch.
