I believe if you hover with the mouse over your save, then press the "suppr" button, you can delete your save file
The delete key works as well. Doesn't help much for Android though. I'll add this to our to-do list of features. We'll get to it... eventually!
oh my, foolish me, i didn't know the "delete key" on keyboard that play the role, hope u do accept my apologize..... >w<
