Hi, we recently released our game Penko Park and I thought I would share it with you.
All of the animations (except a very small amount of 3d animations) are done in Spine.
During developement we had some big problems merging the 2d models with the 3d world. Especially tricky was the interaction of different lighting models and fog with our spine monsters. In the end we managed to solve all our problems with a little help from the spine devs!
