We believe that developers should have the freedom to price their games how they like, without interference from the online stores that sell the games. Why? Because it allows us to promote our games more freely, as we are doing here! We rely on the ability to promote our games for our livelihood and control over pricing is an important tool for this purpose.
Because We May is doing something very incredible here. They are a website to help you promote your game by listing it on sale. Any developer can submit their game(s) as long as they put it on sale for the given duration (May 24-June 1). There are currently some amazing games on sale including Osmos, Super Brothers, World Of Goo HD, and more.
