I like indievania. It is a new, ambitious platform, the overall tone is friendly and kind (greetings go to Lee Vermeulen) and most of all, they take no fees from the developers. Although indievania is still in beta stage, it looks quite nice and has an overall charme that I really like.
So I decided to publish SONAR two weeks before the "real" release on that platform. Don't get me wrong: SONAR is finished and the version uploaded on indievania lacks no feature, has no bug I could encounter so far and therefore is ready to roll.
The release on indievania is something like a test run on publishing for me. Other platforms will follow. I already mentioned Desura (of course) in the comments, and there was talk about GamersGate, who I now contacted. Negotiations, registering etc. with those platforms already has started, so I am pretty sure that SONAR will launch on more than one additional platform at the end of this month.
If you like the demo and you like to support not only me but also indievania as a brand new platform, go there and check it out!
You should consider Steam :o
It has lots of customers and lots of anti-hack stuff...
Take a look...

Thanks for your trust in the game! The thing is: You can't just make you an account on Steam and upload your game. You have to make an application. If there are relevant news, I will tell you guys ;)
