If you're not already on Tumblr, I would recommend marketing your game there. There are a lot of gamers. My games are a different genre but I've built a community there. I actually just posted a YouTube video today on how to use Tumblr to drive engagement for your game.
I also took a look at your game page and I do think there is too much text at once. Use some bullet points and add some section headers/images to improve the experience for those visiting the page.

HAHA I also used Tumblr back in the day but decided to come back when I wanted to get an audience for my game. You have to be strategic but yes, you can find your audience. I've gotten 3,000+ people who are interested in my game to follow my two game accounts. There are almost 200 million people using Tumblr.
