Congratulations on your game's success.
I use reddit a lot to promote my blog posts but I've realized what @chatmasta mentioned to be true.
If you want to publicize your startup or project on launch day, its better to get it published on some famous blog for that stream.
Need not necessarily be techcrunch or mashable. Can also be CSS tricks or Paul Irish's blog. Equally valuable. And the HN / Reddit takes care of itself.
