This is incredible, thank you so much for this.
I will say, the program breaks when you try to build twice in a row without restarting. It only seems to work if I close and re-open it. It seems to believe the image folder is invalid after the first build.
Other than that, this is a life-changing program for me. I make my own living making Twine games, so getting to expand to Steam is a new frontier I finally get to explore. Thank you!!
