...the rules for this jam. I saw the other jam about twenty minutes ago and read over it.  I wanted to know since that one is ending in a day and a half~ish, can I just go ahead and start on the game that I was conceptualizing now?  If not, when can I begin work?

BTW, I LOVE the theme for this jam!

Hi there,

You can think of the concept jam and the actual jam as ... all just one big jam. Essentially the concept period is meant as a construct to allow jammers to dedicate that time for planning things out over the course of the jam, and then take flight during RPGM5. But by all means there is no hard rule as to when you want to start actually fleshing out your game. I hope you have fun!
