Using Leaden Sky animation and movement system is not possible, those games are not compatible at all and use completely different code, character proportions and character physics. The gore is also not compatible with multiple sprites for limbs that Leaden Sky uses for advanced animation.
Ah, that's unfortunate. would it be possible to re-work the health system to make enemies losing health over time make more sense? i feel like they lose health too quickly, and from too insignificant injuries
