I feel that the slide control needs some work. It wasn't too responsive for me and I found I was getting stuck more often than not. Perhaps a click and drag arrow that gives the same amount of power behind each movement.
Pretty fun game and I enjoy how the collectables theme was implemented with collecting your own body parts again. I also enjoyed the taunting you added when I kept getting stuck, bravo!
Overall a fun game, but found myself getting frustrated with it fairly frequently.
