Review Detail of IAmGuavaFruit in Apocalypse, Games, and a Rabbit Girl

Hallo, another shameless author review! So, first off, this book is participating in WPC 242, so it would be awesome if you supported this book by donating some power stones! Ok, shameless begging aside, what to expect in this book. It's set in a post-apocalyptic world, with the MC having an interactive System. And what I mean by interactive, is that there is no tutorial. MC will struggle to find the mechanics of his System, and find new ones later on in the story. Also, as you can see from the title, yes, first waifu is Rabbit Girl. She pretty much looks like the one on the cover. Anyway, peace out, and I hope this typhoon coming my way doesn't go too hard...
