mineet yes the art assets are mine, created with Blender3D the postpro with Gimp. For the girl, I rendered it separately in blender and then join them in Spriter for animation. Unfortunately, Spriter C2 plugin is still buggy. I'll mention you when I get the workaround. Thanks :D.
valdarko it is something related with "on animation finished" event not triggering. I'm currently working on the workaround, I'll post here when I get something. Thanks :D.
