I'm currently typing out a document with ideas I have for a game for the jam, similar to that of a GDD. I just want to double check and make sure if that's okay, or if it's preferred to have that be done closer/during the jam period.
Ultimately it's not something we can police, but you should be doing this during the jam.
It's important to note that the theme will be a major part of both community voting and judge decisions -- so it's unwise to try and come up with any game ideas before you've found out the theme.
Okay. Yeah, that's good point. I just had this idea I thought I could translate into the jam, but I maybe got a bit too in the zone XD. Thank you letting me know!
