There are a lot of very useful replies here, and getting attention (whether this is feedback, followers, views or sales) is a huge issue for all game devs. Two points I'd immediately add:
1) If comments are your main concern, also upload your games to Newgrounds. The comments won't always be nice, or even helpful- but you will get more.
2) Work on your games' thumbnails. People are far, far more likely to be interested in a game with an eye-catching thumbnail. I'm not an artist, but spend a lot of time making thumbs that I'd want to click on if I'd just seen the game. If you are an artist, then you should be able to make something that draws players in quite easily. Look at examples from other games, and try and think about what makes you want to investigate.
Hope this is at least a little bit helpful :)
