I felt the old bat on the site didn't really have much character or it's character didn't fit in with the newer generation of assets on the site. I think this little guy is a bit more whacky and should add a lot of humour to your games.
The download files include everything you need to quickly and easily incorporate this game asset into your game development project. There are png keyframes for each bat animation sequence. There is a fully rigged and animated Spriter puppet, which you can modify, add animations or export up to 4k resolution animations from. On top of that if you need to rebuild the puppet for your own animation rigs there are png and vector puppet parts.
