Thanks for the reply! I opened the game again and yep, hadn't considered it was one of THOSE games. The walls are betrayers. Still, a clearer explanation of that might have been nice. Although I AM DEFINITELY jumping higher this time, along with hearing the jumping sound effect, neither of which I was getting last time. I couldn't have gotten back up from some of the lower screens otherwise, and trust me I tried for ages. I don't know why I'm suddenly jumping twice as high as my first playthrough.
