@beachthunder: No the makers of Frog Fractions are making a game that is as incognito as Frog Fractions was and they are putting it out in the wild with no fanfare when they are done. They are hoping people will discover it organically like they did Frog Fractions. Once it is found they will confirm that the game is indeed Frog Fractions 2 and all will be well. It was all part of the Frog Fractions 2 kickstarter.
Well, in that case, the Hatred theory doesn't make much sense - that has the most fanfare (well, err, reverse fanfare?)
I don't think the plan is to literally release something that no one knows about, it's to release something people don't know is "Frog Fractions 2" (ie, something that radically subverts everyones expectations) until after they've played it. Not that I believe Hatred is FF2, but it could be.
