Yeah, implementing the game itself ended up taking longer than I planned for so I didn't end up getting to develop any story beyond the premise that I started with. I tried to run the map editor myself and I got the same issue, it just opens a white screen and then closes? There weren't any errors in the console so I wonder what it could be. I'll have to look into that because I was planning on reusing the tile editor for later projects. Thanks for telling me!
