This is my first game jam what do you mean rewind? Like something from the other game jams? Helpppppp

LIke you have to create a game from scratch that adapts to the theme(i.e. rewind)

Your best bet is looking up the dictionary definitions and see what comes up? It can mean to revert back to a previous state, like rewinding tv, or it can mean to wind something up again, like a spool of yarn, 

Rewind can mean anything about the game your making. It could be a game about "rewinding" time. Or a game where you "rewind" music and video. Or a game about youtube "rewind". You can do whatever you want around this theme.

Thanks for your help everyone I appreciate it very much good luck!
