I mostly just did this to test whether speedrunning was viable on a controller (and get better at using one while I was at it), overall mouse and keyboard is still obviously better but I did find that using a controller has a few small advantages that might make it a couple seconds faster in some categories so controller is actually far more viable for speedrunning than people give it credit for, it just has a steeper learning curve
never touching this category again, it took me like 7 hours of attempts total throughout the whole week spread across multiple devices and game versions just to get this run
