Aside from submitting the game link to blog sites, I’ve also been submitting the SWF itself to flash game sites, such as Newgrounds and Kongregate. Actually, the sponsor submitted it to Newgrounds. I think they’re also going to submit it to other sites, so I don’t have to do a lot of the SWF propagation work.
So far, OrbBlaster’s garnered pretty positive reviews, managing to make front page on Newgrounds. It’s doing okay on Kongregate, which I think is because it doesn’t have any badges or achievements tie-ins for the site. Kongregate players love the achievements so I might have to implement some sort of it.
Spreading the SWF is a great way to reach other players, but I probably should have put a more visible link to doogog.com. Currently, it’s inside of the Credits button, which seems like not many people check out.
I also submitted my site to the Yahoo and Google directories, and am going to try linkdumps, too.
