I like the concept of a vertical platformer with the constant threat of lost progress, but... Some of the mechanics here don't serve that premise very well. A few of my falls were from obstacles that I couldn't have understood except through trial and error. A game like this is at its best when it communicates clearly to the player. Visual distinctions between normal and falling platforms and better indicators of the tracks that moving platforms are moving along would go a long way in making this a more enjoyable experience.
