This paper evaluates the use of Spine animation library during industrial mobile game software development. The evaluation results showed that the use of both Spine and its supporting tools provides the rapid application of the same animation to various characters, shortens the transfer of animation constructs between animators and game developers and increases the production of required software approximately seven times. However, we also observed that the library was incapable of properly reflecting some of the light events inside games and caused problems in viewing the two animations together.
