Thanks for the review !
You are right that the modifiers don't impact the game as much. We wanted to scales does up the further you got but ran out of time to implement this.
Your other idea of affecting the items inside the bag was on the list, but so low we kinda already knew it wouldn;t be in the jam game.
However, we are currently working on a sequel / actual release of the game in which there will be bags affecting items inside ;D !
