Haha! In that big jump/fall downwards, I was aiming to get that collectable item on the far wall. I was clicking the z and x buttons a ton as I went at that wall, and I got the item, but then I started to drift upwards and my character started flying up without me touching the keyboard. It was probably just a weird bug because I spammed too hard and the wall slide mechanic was just starting to kick in, I probably couldn't remake that bug happen even if I tried. XD
