Ok, first, your game doesn't really show much. It shows a robot and a field. Not exactly very impressive. Try a video. Then we can actually see a bit of the gameplay. Second, there was a post by someone, I forget who, that said something along the lines of "We don't care if you fixed up one map or added one new script, that's not worth a whole updated demo. We don't care and we don't want to hear it. Come back when you can say 'I finished another three scripts, ten maps, and overall about 25% of my game,' or 'I've finished 50% of my game!' Then we'll be interested."
I forget who wrote this, but you get the idea. That isn't EXACTLY what they said, but something like that.
Sorry if I seem like an overreacting prick.
