They might have hoped for a "fully funded in 10 minutes" scenario with the amount crossing into million dollar heights, as it has happened before on Kickstarter. The current result should get their heads back out of the clouds though.
In term of communication it could be a terrible hit or miss too (and more like a miss probably)
The main goal of their kickstarter seems clearly to advertise their game and not to rise more money.
Or at least that's what they are saying, judging by their Patreon post :
"it's important to note that the project Wild Life doesn't stand or fall with Kickstarter, we will always push forward and do the best we can with the means available to us. But it can be a huge step for us and the adult game genre in general"
To be honest, I have no idea if creating a kickstarter is a good way to advertise a product.
I'm thinking of Subverse that worked pretty well that way, however I would say that at the time Studio Fow was already way more popular than Candy Valley Network and popularity is a snowball effect.
I would also say that their kickstarter page is really bland. I have no doubt that people are supporting Wild Life because of the porn.
I'm not saying that Wild Life as a game is bad, but just that if people only wanted to play an open-world RPG, they would probably go for something else since Wildlife would be a little fish in a big pond in the gaming industry.
Porn is a main component of the game.
And I feel that their kickstarter page doesn't show that well. (Maybe it's about kickstarter policy).
