Seeing as how this game is flash based, have the developers thought of making a version of the game to be hosted on one or more flash game sites such as Newgrounds, Kongregate, or Armor Games?
The players on these sites are a vast number of people who will otherwise not likely see this game. On one of these sites there are curently 33,000+ people online playing games.
Another advantage is that the sites that the games are hosted on will often do some in-site advertising for games.
And another mildly trivial advantage is that there may be some returns on the cost of the game (from advertising shares with the sites). Although this will be a fairly small amount of money compared to the (what I imagine to be large) development costs.
