I really like the concept, but I think there are a few things that you could add to make it easier to pick up. The text that generates over the skeleton's head overlaps with the text in the world, so it can be hard to read at times, so maybe adding a highlight or something behind the texts could make it easier to differentiate. Also, when I spawned I couldn't read the whole controls tutorial because it was going off to the right of the camera, so if you adjusted it to be closer to the spawn then it would make getting into it a lot easier. Finally, the movement of the character is unpredictable, so I feel like some people might get frustrated and shelf it really fast. If you had a short bit of explanation as to how it works (what direction each bone will move in if you click it), it would make it more engaging to keep playing. I got to the moving platform with the skeleton's arm, but once I was there I could not figure out how to progress. I still think this one has a really clever idea for the theme, but I think it is too difficult right now to understand and play.
