It's easy to get caught up in people's feedback as well as criticism. I've been guilty of this many times myself. Make the game the way that you want to play it. Atmosphere is so very important for games. The atmosphere alone helps your game stand out above many others just because you are focusing on something that not many fan game creators ever do.
Don't let the haters bring you down. This is easier said than done, I know. This is why I've chosen to take Anathema behind the curtain again for a while as I develop it, because there's no sense in people critiquing an alpha and constantly having to explain myself and that it is in fact, in early stages and things are being polished. My suggestion would be to do the same. That way when you truly feel ready and have a polished demo on your hands, you can let the game speak for itself and people get a true sense of what you are shooting for. It's hard for people to get an idea of what developers are thinking when games are in their infancy.
Make your game the way you want to play it. Either people can get behind it or not. But as long as you make a quality game, you will have people behind. We can't make a perfect game that everyone everywhere loves, so make the game you love.
