The story certainly scratches the LitRPG itch. The characters weren’t terribly interesting to be honest. Being old isn’t an interesting character trait in this world since everyone looks young anyway. There weren’t much indication that being old was even advantageous to the MC. I think playing up to the MC’s classic RPG skills would have improved the story immensely. The overall motivation for the MC to climb the world tree is just not interesting. The bits I thought were good was the magic system and unlocking of surprising abilities.
