Well if the game is good you could contact Armor Games to see if they would sponsor it. If you think you might have a shot at a sponsorship, definitely inquire about it before you release on Kong or Newgrounds.They will not sponsor any game that has been already released on the WebIf they are not interested in a sponsorship go ahead and release on Newgrounds. If it does well you could contact them again to see if they would be interested in a site lock deal.This would be for a flash gameDepending on what kind of game you have, Kong might be a better place to release if the sponsorship falls through.What type of game is it?
At the same time releasing on android without a publisher or an advertisement budget can drastically affect the chances of the game getting any kind of exposure. So yeah, make a plan.
