I had the idea in my head for a while, but what made me go with it was the idea of "digging", a term for Puyo where your board is covered in garbage and you have to get to your chain to pop it. I also had a mode planned where you would have to race the other player to dig to the bottom of your board, but I never got to implement it
I understood that the connection was loose so I designed the story around the jam theme.
