The theme of the jam is Delayed Consequences. 

The protagonist finds themselves ten years in the future and must deal with the significant consequences of a seemingly innocuous act they performed ten years earlier.

How they arrived in the future is up to you: time travel, a coma, suspended animation, magic, alien abduction, or anything else you can come up with.

Some of the game (beginning, flashbacks, etc.) may take place in the protagonist's original time, but the majority of the game must take place ten years later.

Have fun with the jam!
