Somehow it doesn't worked for me to properly include the savestates and some games also just create aditional later version of the game instead of overwriting the old one when I use the app.
Being a game in development, it is necessary to start a game from scratch to avoid compatibility problems.
I assumed it's just something I don't know how to do correctly yet. Okay then.
Hhhhmm I think I have to wait for a bit more then, just to be sure I don't get bore to easyly by running into dead ends.
