Great concept you have here! The ideas of bones and limited movement makes you think a lot about what you should do, and I like it! But I think I got stuck in a level because the number of moves is greater than the number of bones I had, and that made me think that probably the number of bones should be always the number of moves? Because there's no need to have 20 bones and just using 5, in my opinion
Other than that, the graphics are simple, but great, and the introduction is very nice! Music is chill and very good too :D
