The site looks nice. It looks like a fun site.
However, from an SEO perspective, to expand on Sparks199's comments, there are a lot of flaws.
This starts at the top of the page with the title tag. The title tag should be no more than 64 to 74 characters long (depending on which expert you believe).
It is your most important SEO real estate, so it should include one or two keywords. If you can squeeze in a call to action that is good too, but that can be in your description.
You don't have a lot of text. That can also hurt your SEO efforts.
SEO is all about text. You need to have your keywords, plus semantically related words scattered about your body text.
If you fix the stuff that Sparks199 mentioned including the title tag and add some text at the bottom of the page, you might get a lot more traction from the search engines without doing much else.
You're doing a lot of other things right.
