a few advices
*work on the collision of your platforms,i got stuck in the middle of one a few times already
*you should make a min. jump lenght, that makes the game a little more soft and easy to play, later on you can add jump strenght by holding left click.
*a personal advice, before asking for feedback, make sure you are happy with your game before even publishing, that way you wont get that much hate, plus you check for bugs that are easy to fix and bothersome
