Just wanted to tell you guys I got to use Spine in Ludum Dare 27. Had a great time, and spine made my life a lot simpler. The theme was 10 seconds, so I got to animate a pocket watch . I might have gone a little overboard and made the watch take up way to much of the screen when winding it up, but I was just having fun with it. Basically everything in the game except the tilemap was animated with spine.
Let me know what you think!
