well said! you echo a lot of my feelings that have accumulated over the years. in some ways gridcosm teaches you to let go. take a deep breath and let the level pass. in other ways, you get so attached, you can freak out at one little pixel rubbing you the wrong way.
however, i love best how you summed up the immortal/impermanent qualities. if something is that self-contradictory at its core, how can everyone be happy? or ANYone?! and how can we NOT?
