I just started looking at speedrun games and wanted to try only up. I didn't want to go through the painful process of playing the game, so I started glitching through the map. I found that you can clip through the wall at the start with a bench and precision. Then I proceeded to jump on top of a roof and then tried to spam rolls. I didn't think anything would happen, but the character started moving up the invis wall and I got up another roof. I don't know if anyone has found this yet, but I just wanted to recap what I just found. Thanks Joecooley
