This was one of the first Indie games I ever played and there really is no other game like it. It's nice to have a game that focuses entirely on ambience and relaxation and not challenge and controls. It really makes it more of an experience than a game, and there just aren't enough of those around.
I played it over a year ago and always come back to it to chill me out, I'm so glad to hear that it's being expanded into a larger game. That being said, I do think that 'Fruits of a Feather' is a much more unique name than 'Feather', but I'm thrilled to see that the aesthetic style is staying the same. My other piece of advice would be, RELEASE A SOUNDTRACK! The composer did a stellar job, it's some of the best in any game and I would love to listen to it while doing other things too.
Sometimes, less is more, and that sentence sums up the success and gameplay of this game perfectly.
