Wow, I really liked it, it was like a drug :D! I really enjoyed it! Congrats!
P.S. One little suggestion, When you are controlling the cost you can't jump, my suggestion is to make the most jump. Many times I had to restart because I missed/misclicked the body and I jumped down without a body to kill the other mobs, and I was tucked there :(. In any case very enjoyable!
