Just a thought for the next update, could you add a save export/sync method for transfering between devices?
Both 'New Family' and 'Go!Go! PizzaBoy!' have this where it makes a link/code to the Ren'Py sync servers or smth that you can put into a different device. It's been quite useful since getting a new device and wanting to pick up where I left off!
Keep up the great work :)
