Review Detail of TheF16 in Game Tester in the Apocalypse

Didn't find too many mistakes, the story is addicting and gets you hooked easily. It's about a fatty who does game testing for a living while part-time streaming, He got into game testing after getting fired (he got bullied there --> it's something that reflects on his personality). Apocalypse started when he accepted the invitation from a mysterious game company to beta test their new game "World Simulation". From what I understood, it's a game about surviving at the end of the world. What's most interesting about becoming a beta tester for this game is that reality starts becoming more and more like game (the game has real time feature, bug fixing). In conclusion, from the 20 chapters that are out, I rate this novel as a 4.4 with 4 in writing quality (didn't see any gramatical erros, but english is not my native language so what do I know), 5 in stability of updates (2-3 chaps a day), 4 in Story Development (didn't give it a 5 since I don't exactly know how it will develop), 4 in Character Design (the characters feel real, but I'm a loner so don't trust my word for it), 5 in World Background (don't know why I gave it a 5, just move on to other reviews or start reading the book).
