Steam is very important milestone for us. We are developing this game purely from our funds and they are not very big. Getting onto Steam would allow us to keep developing game further. If you would like to see full potential of SpaceCube Arena, vote "yes".
Right now we are working on feedback collected from comments. If you have some ideas for us, in which direction we should go with SpaceCube Arena, write it in the comments. We are seriously listening all the opinions.
