Delete all the incomplete games in one go?

As the title says.. I normally restart games specially when I mess something up right at the start.. maybe a button for deleting them all? Thanks.

I just write my save code down, clear data in settings > apps > mazebert > storage. Reload game login with save code. All old games removed and game running smoother

Cool trick. My save code is memorized a long time back. 😅. Thanks.
