not too sure if im an idiot but is the andriod ver working? "App not installed because package is invalid" 

Also dev if you do rewd this holy shit you made peak

Same happening to me

You need to uninstall the game first

But if you don't export your save you will lose it

To do that follow those steps:

1.Open your old game.

2.Main menu => Load => To File

3.Move the file where you want to.

4.Uninstall the old version

5.Install and open new game's version.

6.Main menu => Load => From File(And select the exported save)

Tysm dev I saw the thing about steam which is a real shame. Thank you for making such a good game though.
