statham if you use physics behavior for your player, it's better to move the object by applying physics force to it instead of directly moving it (it can mess with the physics). Here's a new capx where the rotation is fixed and movement is made by applying force at angles 0 (right) and 180 (left) degrees instead.

You can play with the physics elasticity and friction settings on objects if you don't want the player to bounce when hitting surfaces etc.
If you don't really need physics and want the player to drop straight down instead of flying to left/right, you could also just use a platform behavior for the player (with default controls disabled) instead:
