Wrong. The rules state:
All assets and code must be created during the 7-Day time period of the jam
You can upload a new zip and delete the old one, yes. Or you can leave the old one and just upload the new one with the version number bumped up (if your release names have numbers in them).
Thank you for participating in our second GameDev.tv Jam! It has been incredible watching the community come together, form teams, and learn together. I know some teams were unable to submit for various reasons (incompatible work ethics, disagreements over game design, technical issues), but I hope everyone who participated learned something and has become a better developer because of it.
For the next two weeks, the jam will be a hub of ratings and feedback. Please remember not to take any feedback personally! A player's comments and suggestions are an expression of how they felt playing your game, and it is always worth taking their words into account in order to improve your own game design skills moving forward.
Lastly, if there is any entry you are particularly impressed with, I highly encourage you to study the source and even reach out to the developer about how they created the game. We all have different backgrounds and skillsets, so who knows what we can learn from each other.
Have fun playing, rating, and learning!

Hi, thank you for submitting to this jam. Please do not upload PNGs and scripts. Source means everything needed to compile your project, which includes materials and prefabs. Please zip up your project and submit that for the source.
