I uploaded my game in alpha this summer. I only had one level, but I figured it would be a good way to gather feedback to release it early, and it was! However, I was wondering what I should do when updating the game. Is it better to upload a generic filename and reupload the same, updated file with each new update? Or should I delete the old file and upload a new one? I noticed the stats on the dashboard disappear when you delete a file, so I assume it's better to just reupload with the same filename? Also, does it have an impact on how the game is displayed on the main site, and which position it has when browsing?

Thanks for letting me know.
