We had to rework a lot of the levels during the final sprints of the project as the older ones didn't really work with what the game turned out to be. We'd love to have a longer game but time is a real tough enemy :p
The jury we presented the game to got to see a presentation with the (somewhat loose) backstory to the game which will explain the reason for the actions in the game, sadly we didn't really have time to explain everything in-game!
