I see you suffered a few hate-votes on Newgrounds too and the game is rated stupidly low. I'm getting a bit suspicious, because I've seen some truly awful games with 4+ stars and some really good ones rated down at 2. I suspect people are getting friends etc to vote up their games because some are very bad. 2.4 for Board Horde is totally unfair. I'd understand it if every game was down at 2 stars because some of the haters state really stupid reasons for downvoting (I've seen people vote a game at 1 because 'I don't like shooters' and it's common to get a 0 vote because it doesn't work on their machine, which is sort of annoying). But some really weak games get 4 stars which is really strange. I think the main trick is to get rid of every bug and get it working on every platform and then re-release it, because that will kill most of the hate-votes and you should get closer to 4. I've added my vote :)
I can't believe someone said the music was annoying, I love it. I found myself humming it while walking to dog, lol!
I guess the point of Newgrounds and Kongregate is to test out your game. Release it, see the response, fix the errors (would help if they'd reply when they find bugs) then release it again. Eventually it should be completely ready to go.
Still, it's a bit lame that my new Jovian War game, which took about 20 hours to complete, got more than Board Horde which is far better and probably took you 50 times longer. I guess the point is, my game is simple and doesn't have bugs or issues on other machines, due to the simplicity. For now, it seems like that way to go.
I'm not sure where to go after the Newgrounds route etc. I guess marketing it on your own webpage or other places would be worthwhile. Not the sort of thing I know much about unfortunately.
