Hi guys, I have open sourced a tool developed internally by us for sprite animation checking. Basically, it allows you to upload a spritesheet which you can then adjust and edit on your browser to make sure the animation is smooth and without any twitchiness. You can try out a demo here http://www.azukisoft.com/OSC/ For the source code, you can get it from Github https://github.com/gibtang/AnimationChecker
