for the boxes since each player has 2, we had 1 spawn at the top so you can't access it directly, but the other one spawns randomly in 1 of 4 places. In future versions, do you think having both boxes spawn randomly would be more fair, or the box that spawns randomly spawn on the same level for both players (symetrical level design)?
For the castle stage, since the focus is more on using moving platforms to your advantage as well as some of the juts that prevent you from going at high speed, we decided to use only 1 predetermined jar for each player.
