heym nice concept !
I love platform puzzles and this on is cool,
It takes me some trys to understand that I can jump when removing a platform, but once understood the levels were mush more easier xD
if you want to add some accessibility, it could be ok to add a little delay on the disapearing of platform I guess, to let the player know he can jump (or maybe its just me that is numb ><") ?
anyway, great first game I enjoyed it a lot !
