Do I need this or can I delete it?

The only .txt file you really “need” in the scenes folder is choicescripts_stats.txt (assuming your game uses the character stats screen at all–it doesn’t strictly need to, of course) plus your game’s .txt scene files.

You can delete it, but remember to delete it from the sceneNavigator in mygame.js as well, so that if the scene before that ends, you don’t get an error about “Invalid Scene” or anything like that (I’m not sure you do get an error, because it never happened to me, but just to be sure).
