There's nothing wrong with the concept, but I think the fact that there isn't enough contrast between the text and the stars is your biggest problem. Also the image lacks depth, there's no indication that it is space - really its just a bunch of white dots. Is your story about space? or is it designed to indicate the vast-ness which is space? Whats its relevance to your game? You're font clashes a lot because its white on white dots, the glow makes alot more bright color surrounding the font which also reducing the impact of the text.
If you work on it, I would recommend making a visual focal point. A core to the image. Looking at this title I really have no idea where my eyes should be looking. The addition of a planet, or logo would help a lot. The actual font represents a classical era, where the background represents a futuristic era with the swirls of color. The color gives of a very "Clarity-fresh" feeling but there's still no visual focal point which really leaves me thinking - "K, so?"
