from about section:
Comic Ad Network is an advertising & ad publishing service created by comic artists for comic artists-- But that's not all! We also welcome authors & writers, animators, digital & traditional artists, game creators, anime enthusiasts, and more!
it does have mostly comic artists but I've also remember seeing some sites with web based games
but yeah, this is not a strict platform like tapas that accepts only certain types of files, you pretty much just need to have a website that you post to that you can edit to get their ads code into (so, you can't for example use your work's page on tapas since tapas limits too much how you can edit it)
