Another indie game dev (well, student) here.
You should look into the MARKETING, first and foremost.
Make your website look like something trustworthy, professional and cool. Your link opens something that is... none of that (1680x1050, Firefox 27.0.1 on Windows 7).
I'm sorry, but I don't want to enter my Facebook crededntials for a site that looks like that.
Clicking the "register" button opens a new tab, on the BACKGROUND so I might not even see it, and the page that opens is for registering to your forums. Is that the same as registration to play the game? You never tell me that. And I don't know how long a single game will take, if it's a fast consecutive game or slower turn-based one or if both ways are options.
Also, this thread and the links I follow won't tell me anything about your game. There are no links back to the home page, and there are still many people who won't bother changing the URL to get to the front page.
On the bottom of your main page, you mention "We will be launching our Kickstarter soon" - you had it already! Fix that!
The game itself looks like fun, but you neglect to mention that the game is inspired by the real-world games like Mafia, Werewolf etc. When I search for "browser games like mafia or werewolf" I get your Kickstarter but NOT your main page! Look at the successful wording you had in your kickstarter page, and update your home page to match, including mentions to the kickstarter page.
Making a game is only half the battle. Look into how to get new players interested, how to hook them in.
I hope the awesome wolfire guys dont mind stuff like this.
