Literally within two seconds of uploading my game to Newgrounds it received about three zero votes. Also there was someone bragging on the message board recently about how he voted zero for every game entry, for absolutely no reason. Still, there are some decent folk there who are willing to provide feedback (including the judge, Tom Fulp, who took a lot of time to analyse as many of the 95 game entries as he could) and I can see how the html5 gaming community could really take off once Flash takes a backseat, so its worth persevering.
There were some games that I didn't like much which made the top ten, and others which I liked a lot that got barely above two stars. A lot of the time it can come down to personal preference, or something as simple as whether the game actually works on the browser or device the persons using; even though some creators put on the front pages of their games 'works best in such and such a browser', if that's not the browser that the player has open then he'll try it anyway and rate it badly if it doesn't work (and then leave the comment 'didn't work' without saying anything helpful that'll assist us in improving our games).
What I found a bit odd about the competition is that you could vote for your own game once a day (which I didn't do) which may explain why some of the less polished games pushed their way to the top. At least when it came to the actual judging, it wasn't just down to selecting what was at the top of the list.
Farflamex, thanks for commenting on the music. The musician did me a huge favour at short notice, so its nice for her to have some positive feedback.
20 hours to make your game is pretty impressive going! Board Horde has probably taken me about 400 hours so far, and it isn't even finished yet (then again, its my first game so its bound to take a while)
Anyway, before I get back to the joys of game creation, Excal I'd just like to say that I really enjoyed playing your game. The touch controls are probably the best example of their kind, and I had great fun trying to work my way up the leader board. If i was making a top ten of my favourite competition games then yours would be in it (along with Bunker Control, which also fared quite badly). I really look forward to seeing what you do with the game next.
