I think you should have feedback before or when the platforms move, either auditory or visually. It feels a bit jarring to just have them disappear. The first few tries I did not even realize they disappeared after some time, because that always happened when I hit the second platform, almost thought it was bugged.
The concept is really neat though, especially starting right out of the menu!

I did think of adding some sort of visual cue......but I felt it would be more challenging without any sort of feedback. This way a player has to be more alert and move quickly.
I realise that the movement of the platforms is a little sudden....maybe I could implement a new system after this jam.
Still, thank you for playing my game :)
