There's only one ending and it's bad, however there seems to be themes about overcoming destiny and fate. So a long three phase fight that can only culminate from recruiting as much darkners as possible, gathering all shadow crystals, and being as nice as possible to everyone in the light world.
Phase 1.
Each shadow crystal takes a turn becoming the different soul colors, forming a prism that amplifies light, this phase fails if you don't gather all shadow crystals

Phase 2.
Each worlds darkners appear to give their support, each chapters secret boss creates a path forward for The Shit Squad

Phase 3.
Each Lightner that's been to the dark worlds appear to give Kris their light, further amplifying your souls brilliance

From Kris bursts forth a Titan of Light, to bring balance to Light and Dark once and for all
