Glad you enjoyed! As of right now, no, there is no definitive ending to the main story, the reason being is that I'm planning on adding more worlds, I'm actually working on the 6th right now. I have a plot planned for the gods that would give some sense of story resolution, but it most likely will be only generally tied to the worlds (ie. scenes only unlockable after beating so many worlds) so I can expand as wanted. For now, I recommend going through the worlds again if you haven't already, since each world you beat unlocks a new scene in another world, and there are various routes you can take through each.
