For some reason I didn't receive a notification for this, so sorry for the late reply. Anyways, on top of the fact that I have forgotten most of the issues that I was having, some of the methods I use to play RPG Maker games have updated, so I need to re-test the game now. It may take a while because things in my life have changed abruptly, but when I have time, assuming I still can't get the game working, I'm going to create a google document to compile the issues I had with screenshots for each method I try.
And yes, I fully understand that Windows might be the only platform you can actually help me on but I'd prefer to get it working on Linux and android, so I will still add both of them to the document, just in case the issue is somehow caused by game itself and not caused by the method I tried using.
But for now, the only issue I actually remember is that, on Windows and something else that I can't remember, the bottom of the screen is obstructed by a black rectangle. I can click through it but I obviously can't see anything behind it.
