I had read a post stating that you could not update games in the arcade. However I also so that the forum post was about a month and a half old, and Tom had stated that it would be supported soon. Has this ability been added yet? I would like to upload an incomplete game for some feedback and advice, but not going to do so unless it can be updated.
I looked around the forum and did a search but could find no follow up stating that it was supported yet.
