So I just finished it and...

Is there no sort of free play or whatever? You only need 4 keys to get the ending and you get 1 key for each villain ending you get (3-4 story potions). Obviously that means you can't read all their ending routes (I'm assuming 2 for each of the 7 villains). But after the credit rolls, it just returns me to the ending scene again before the credit rolls. Do I HAVE to delete my save data to experience it all again?

Yes. Hopefuly there will be DLC
