Hey,
Sorry, this thread is a little old. But it's the latest in this particular category and it hasn't had any responses.
I purchased this game yesterday and I must say this game is pretty invisible. I found it when I was browsing thru the list of the 2009 IGF entrants.
So, trying to increase the awareness of this game:
First obvious solution is have it distributed on more portals. That seems like a no-brainer to me so you've probably already thought of this.
A second thing I notice was on Bit Blot's website, well specifically Aquaria's website, they have an "Indie" section:
http://www.bit-blot.com/aquaria/indiegames.htmlThere they have a bit on other indie game companies/games. Now it's up to them if they want to do that for you, but maybe you could do that for them and build a connection with other indie developers. Both of you would benefit from each others traffic.
