Yeah my project file is 10gbs zipped and completely compressed in unreal so I'm just gonna submit my google drive link and hope that they are fine with it. Would've loved some communication from anyone really about this but I hope they understand.
Do you mean where, because if you mean where. I put it in the box when it asks you to put your github link and instead I put in the link to the google drive. Make sure you already submitted your game to itch though and then you can submit it to the game jam. If you actually meant why, which it feels like you didn't because of the wording. I did it because in the last game jam someone made a comment about if they couldn't submit to Github and if they could use google drive and Otto said that any file storage platform was ok. I'm not sure if that has changed since he hasn't replied but I sure hope it hasn't.
