The plantgirl is done before my message, and if the industrial zone is the area where you can be trapped by the glass tube, then I went for a ride. I will revisit the area in case, when I have time.
For improvements, too bad for me. ^^ But if one day you plan to rework the game, with new files, I would be perhaps one of the first to test.
In the meantime I will follow your advice (Alt + enter & volume mixer).
Good continuation ;)
