Neat idea and backwards take on the infinite jumper format!
When do you want to jump? I haven't quite figured out when that's useful.
It also seems like there are platforms far below the bottom edge of the screen that you can land on if you're lucky. Made it feel like sometimes I got a second chance, but it seemed more like a bug than a feature. On the flip side of that luck, sometimes I just fall through a platform on the screen.
