I stumbled my way back to my flat and collapsed into my nice warm bed. However, when I opened my eyes to the new day, there was no light. Only darkness, with the words "Welcome to Planetary Avatar, become a level 3 planet to continue to stage 2." popping into my head. What the hell is this?

The first proper novel, please be kind and make a review. If anyone would like to, I would appreciate if someone could proofread my work too so it can become better. Thank you.
