At the bottom of the Options menu, there is a Delete Saves option!
[Oh ok thanks Devs in that case.] (I have another idea for an update how about you add the ability to become a genie or a jinn to the desert map allowing players who chose not to be a succubus to become something else and if a genie or jinn doesn't sound good then there is other things you can add that the player can choose to become or not but that's just a suggestion so I hope it gives you some good ideas for future updates so thanks for reading Devs.)
