I had to change my review. the mc's personality is way too inconsistent for my liking , he came off as a pretty cool-headed and intelligent guy , then he just turned into an incompetent child out of no where , who forgets they have a rifle in the apocalypse? he creates games but doesn't know to aim for the head when fighting a zombie ? Secondly, the power-scaling is incredibly vague , he's killing zombies ( who have regenerative abilities for whatever reason) and it's not showing any indication of his strength gains other than his rank in the world rankings. his overall prowess is hard to judge.
