The game is fun. Restarting from the beginning when you die is a little to harsh in my opinion.
Technically can be improved, movement and shooting seems a little bit off. Maybe it needs a limitantion for how many bones can you shoot simultaniously.
Really love the art style! Some sound effect can improve the experience. And a side note for the music... I thought there was none and I had the volume at maxium, I almost jump on my chair when it started ahah.
