Is there any way to wipe your old save files so the list doesn’t get so stupidly long?
For that sort of question you might be better emailing choicescript support and asking them.
I’m almost certain there is currently no method for user-end deletion.
I asked the same question, a few days ago. The answer is: No, not yet.
This probably has something to do with the fact that authentication is done via email only (no password) so it’d be pretty easy for people to maliciously delete other player’s saves.
