Oh, thanks for testing the mobile version!
With the current (unreleased) build I'm working on right now, it should -theoretically- be able to load the old save file, however, I've made some changes that may break the game's UI if you use an old save file, so I wouldn't recommend that. Additionally, if you're sticking with the Android build, I've previously addressed that the mobile version won't be receiving any update until after I complete the game, as stated here, as I will have to customize the UI for a more comfortable mobile experience (which, again, can only be done after finishing the complete build).
(Dw, it's not cheesy!😄)
