I'm currently working on the ONE thing that requires quite a bit of work with its animation: A singing totem with 4 freaking heads. There's about 500 frames of sequenced animations and I'm at the 310th frame done.
I could have done a much better work on the model and the armature/bones, but I'm saving that time for the new gameplay mecanism I just revised.
(For the commercial release for the end of next month, I'm planning on having a system to customize the totem, hence that one will be scrapped.)
The new gameplay mechanism is a mix of Tetris' controls and sequences and Snake set in a Maze where you goal is to guide souls of the departed into the afterlife.
Long story short, that totem is Ba-ho, a guide that has a flame above its head that attracts lost souls in the Ukhu Pacha (Inca's underworld). Think of it as a representative of Pashamama, Goddess of fertility that guide the souls back to Kay Pacha (Inca's world of the living).
I don't think I'll be able to reach that far in the project by the deadline, but I would really like to be able to bring in the Supay, demons that would stop the souls in their track.
