My main point is that it is far too easy to completely break the game, using just the key configuration menu.I feel like this desperately needs to be addressed.
After much more testing, I can conclusively say that plugging in a PS4 controller via USB just doesn't work.I even tried using "DS4Windows" to make the game think it was an X-Box 360 controller, which didn't change anything.
Sorry, I dont have a PS4 controller and have not been able to verify that. But I hope to suppot it in the near future.
Thank you so much for answering that question! yes, you can initialize the settings by deleting "setting.sav".
