This game's style really looks amazing and I'm sure I'll pick it up at some point. Adventure Games were the genre that really got me into gaming and computers way back with the original King's Quest. I backed the Double Fine Adventure.
However, based on this review and John Walker's at rockpapershotgun, I already know that I'm not going to truly enjoy the game. The first thing people say about a great Adventure Game is that it's all about the story. It looks like this does have an interesting story, but I'm not sure if this is really the best way for a game to tell a story.
Something John Walker mentioned was the let-down you get from finishing some of the puzzles. Really, the pacing of Adventure Games is a problem. You move about the world, explore, and talk to people and that's great. Then you get stuck on a puzzle. At that point the game just seems to stop. When you finally rub enough items together to proceed, you maybe get a little more story before hitting the next wall. If the puzzles are too easy you fault the game for being just an interactive cartoon, but if they're too hard the pacing is terrible. I don't see how this can be solved.
Another problem is that Adventure Games are extremely linear. There's usually only one or two ways to solve a puzzle, and you only affect the world in a couple of minor ways. The world's often don't really feel alive.
When I look at Night of the Rabbit, I really want to explore that world, but I'm not so sure that I want to do it in the form of a very traditional Adventure Game.
