I love this take on the theme. 

playing it cost me an arm and a leg :)

Fun idea to use the player's bones as ammo! Altering the player's movement based on the bones they have left is also great, but I found hopping to be a bit more annoying than crawling, so I actually preferred to have one less bone in that case. I also think it should be possible to pick a bone back up if you fire it and miss; I ran out of bones pretty quickly because of that. I personally don't have a lot of skill with this style of game so I died quickly, but it was still fun to play while I lasted!

I really like that losing a bone has serious consequences, and the leaping was a funny touch. The game quickly got repetitive tho!

I'm almost certain that the game will take the first place in terms of enjoyment.

Good use of the theme, quite fun, good work :p

Awesome game! Very cool gameplay idea, feels very fun to play.
