After playing it for myself, I have a few personal interpretations of what the deeper story could mean. The biggest standout theme, to me, is the idea of a cycle and rebirth. At the end of the game, the main character destroys the big giant flying bug thing and we see it seemingly absorb its power and become a giant bug itself, and from this power it creates a number of new worlds that grow out from one another. This idea is also kept strong by the game's name, "Cocoon", since it is related to the life cycle of a butterfly and the end of the game can be seen as the main character coming out of their own cocoon. The other slightly weaker theme I came up with is the idea of scale and one's place in the universe. Not only do we see a host of other creatures identical to the playable character, solidifying the idea that they are just another of the creatures within the world, but the game's whole premise of traveling between worlds and messing with their size kinda gives off the vibe of seeing how miniscule we are in the grand scheme of the universe.

So while it's mostly left up to interpretation, I think this game has a pretty strong thematic hold, and in fact I think its debatable nature makes it a little more engaging and interesting to come back to and talk about. But thaaaaaaaaaat's just me

Honestly, I can completely understand that view on the story and I think that if that was what they were going for then I can definitely see how impressive it is. I also think that the rebirth and cycle theme can tie into the intentionally repetitive nature of the gameplay and it not only leads to the cool puzzles but also helps deepen this theme. I definitely enjoy seeing a lot of people's different perspectives on the story, even if it hasn't made me love this game any more than I do. At least not until I replay it and catch up on all the little things I missed.
