There is a way for you to preserve save files on android, as pointed out by someone on my discord, but I did say in the dev log I posted for 0.2.0 that people may need to re-install the game. Again, sorry for any inconvenience I've caused you.
Ah okay. I'll have to check that out in the future. And no worries. I'm a bit annoyed that I have to repeat everything but it's a really good story so I don't mind it too much
