Very interesting mechanics with the resurrection of skeletons and controlling them with the help of bones :D
I liked how the control tips are integrated into the game itself, the tutorial is very well built!
On my first playthrough, I ran into a problem at the beginning of the second level, too many skeletons fell into the pit at the beginning of the level, which prevented me from advancing further and climbing up the ledge. I had to restart, but on the second attempt I went through to the end!
Great job :3
