After funding the KickStarter, but not getting to play or run it yet, I finally got to play this at Big Bad Con 2016 at a convention game. The game does such a brilliant job of allowing you to play prey. The world is a rough and dangerous place, and you feel it at every turn. At the convention game they had the accompanying deck of cards, which is a nice touch, but by no means necessary.
If you are familiar with PbtA (Apocalypse World-based) games, then you will already be familiar with the success / success with complications / fail forward mechanics. One thing that differentiates this game from many other RPGs, is that there is really not much in the way of "combat". Being prey does have its disadvantages. That said, one brilliant mechanic in this game is the Innovate move, which allows you to cleverly come up with new moves that your bunnies discover or create. In our game we created "Speak for the first bunny" (i.e. Proselytize... i.e. Religion). A nearby table innovated a move to start fires, in helping fighting off the humans... but which resulted in a complete forest fire.
All in all, I can see this working equally well with younger audiences, but also can be brutal and dark with those that want it so. It also allows for easy progression of new characters in the continued tale-telling of the same rabbit warren, which means that even though characters can die easily, that doesn't have to stop the game.
Great game. My writeup of the con game is somewhere in here: http://www.supernovembergames.com/tomes-of-tomes/2016/10/19/big-bad-con-2016-saturday
