About movement. It felt weak, until I realised that you can charge it while moving, which is counterintuitive for me, but it benefits the system. Maybe you should teach the player that or maybe I just missed it. Other than that I would say that it feels perfect now.
The gameplay loop get's boring quickly. I agree with the comment that states that there are too little object to knock. After that it's just running back and forth, until you die.
I can definitely praise the graphics, and audio fits well.
