It's clear that you've put in a lot of work since the last version. The game looks and feels perfectly consistent right now. Great work! I adore the delicacy of the characters and the universe you've created. The sound design (both effects and soundtrack) definitely voices that as well.
For future iterations, you might want to revise the level and consider the story you're trying to tell to draw the challenges. For instance, I wonder why did you decide to spawn the characters in the middle of the scene and have a platform to the left and a barrier to the right. For this case-specific case, I would reference Super Mario Bross, where you guide/introduce your player by moving only forward (to the right). If I have two spots in opposite directions, right in the beginning, that might get confusing. Still, I adore your game.
