@Nickfost I'll try to be constructive, altrought my subjective feeling is that you may need to gain some more experiance to start this kind of business.
You site's bg image is 2,1Mb. It's extremely slow to download even in a 10Mbps wired connection, but in mobile.
I see that you have an idea, I also have several ideas in a month, and 95% of them is ending when a competition analysis is completed.
Your model is a working one, but you may have to have some unique selling points to stand out, and be successful. We have an exporter for Kongregate.com for example, what uses a revenue sharing modell with 25-50% of ads income. KG already have a big weight, good amount of users, and several special functions to use - like scoring, leaderboards, etc... And another example is Clay.io, what can provide in-game-purchase, and takes only 30% of the income.
I see that even with lots of competition there is a way to be successful and noone will protest if you make a site what have several thousands of players a day.
If I will look at your final site, my very first question will be: "Where can I access the ads statistic?" You need to make it available instantly for developers, even if this is not so easy... (There are ready to go Worpress membership/revenue sharing solutions).
Wish you a good luck!
