Review Detail of Nikideema in Digging to Survive: I Can See Hints

I read up to about chapter 150 or so. I truly enjoyed the concept. You have a mixture of survival, gaming, crafting, and a system. What could go wrong? The first few times the MC dug into a new chamber it was interesting. He would get some new items, fight some monsters, level up and upgrade... but by the time you have him going into the 50th, 60th, 70th chamber it gets mind numbingly boring and repetitive. The only thing that changes is the monster's name and maybe the skills he uses. You can even consider each chamber as a separate story and episodic section that happens in 1 or 2 chapters at a time that is self contained and doesn't really affect the plotline of the story other than be the mechanism for him to get new items.
