Hey! Thanks a lot for replying at all. I made sure that i copied the file several times, and i've noticed something particularly odd.
The persistent file in my phone weights around 671 kb. When i move it to my computer, start the game and make Thanatos tell me the amount of medals, the file drops its weight everytime to 301 kb. I don't know why this happens, but i just wanted to come back to you and let you know that i was unsucessful on making this work.
Considering your reply, my theory is that the difference in format is not being recognized by the game in the computer, which causes the game to just recreate the persisten file back from zero.
Thanks again for your time replying to me! I love your game, i will just finish it on the phone :)
