I enjoyed the game and concept, the levels that had horizontal wrap around were great. I think during gameplay the soft-ground levels provided some frustration - nothing like falling thinking "Yeah!" then hitting soft ground that was off screen and surviving :P - and the mechanics of the hight being calculated from the platform you left rather than the height you fell from definitely tripped me up on level 14.
Not complaining about the soft ground, it definitely added a level of complexity to the concept but if the mechanics for falling stay the way they're currently setup I'd find it helpful to have some onscreen indication of where my fall was being calculated from.
Keep up the good work!
