The gameplay was pretty rich for a platformer of this type but the controls felt quite unconventional for me, so it wasn't very easy to get used to. The pixelated videos between levels and on the death screen feel very weird! not necessarily in a bad way. I guess it gives a unique feel to the game. Also, in the first part, the background elements are not supposed to move like this when the character moves! I know it's supposed to be parallax effect but the background should only move relative to the position of the camera, not the character.
