For one big and important thing, the first 5 levels are replayable without needing to reload the map!
Other than bug fixes (hoping I hadn't missed any while testing), nothing much new has been added (other than a better boss in bonus level 2!). Again, please ignore that the map is said to be supported in 1.7, as there are snapshot functions (14w21b) that are required to have the game work properly!
