So after two months, this is how much Gravity Storm sold:

itchio Sales: 1

And this is after putting my game on sale a couple times and itchio gaving me an actual good amount of visibility. I was actually planning to take down the itchio version, but since someone actually bought it, I won't do that. 

Steam Sales: 85

Steam wishlists: 1,089

Steam wishlists are getting more and more worthless. After some research, I learned that the average wishlist-to-sale convertion was 10% to 20% in the first week of release; however, it's around 10% now. You can blame it to so many games coming out and people wishlisting compulsively. Wishlists are still useful, but expect most of them to be dead. 

A lot more could be said, I usually add more info and many nice graphs, but I don't feel like it today. 

Thanks to all of you who bought and played Gravity Storm, I hope you had fun, and have a nice day.
