Note: Using the mesh deformation to animate your skeleton is fine if you will use the animation to create a video or still images, but generally weights should be preferred if you will use it in a video game or something using Spine runtimes.
By the way, if you would like us to check your Spine project, you can send it to us via email: contact@esotericsoftware.com
