mostly fixing the bugs that plagued our demo

Added extra platforms to the swamp level
fixed the kill scripts and jump buttons not giving out proper audio or not working
made the end cutscene return to the main menu
fixed the build errors that were still popping up for some reason, even though the project could build
re-added level 5 for testing features like new jump (will be removed for final build)

removed all of the old builds (I made a backup of the previous master with all the old builds though)
