Let's say you have 10 levels, and in the last level you beat the boss, and you win and finish the game, but later I added more levels, and level 10 would be level 15, so I want to add more 5 levels, would that work? So the final boss in level 10 would be in level 15, how do I do this? What if the player already finished the game, would he play the last few levels again?
Why would you want to add more levels then have the same player fight the same boss level at the end once they have already completed it? You are much better off adding a new zone of levels. But to do this, say your Boss level is 15. Change this to 20, then add 4 new levels as normal, with your newly named boss level at the end as 20. Then reorder the alignment of scenes.
