Okay so if the unlikely circumstance happens, where you prototype your dreamself with a doomed version of dreamselfsprite who has been prototyped only once, would you be able to godtier still or would yousprite^2 count as a seperate entity than your dreamself, being comprised only your dreamself?

Your Sprite Squared doesn’t count as your Dreamself anymore. A Sprite Squared is, by definition, the Ultimate Self of everything it’s been prototyped with. As such, it wouldn’t just be ‘your Dreamself’, it would be every single iteration of yourself packed into a single entity. The embodiment of the potential of what you could be.
