Review Detail of BlackMango in What?! I Reincarnated As A Lizard?!

I'm a sucker of isekai and all but I get peeved by inconsistency (attribute status panel) and unreasonable choices. The book struck me as a copy of "I am a spider, so what" but that did not bother me much. I found it illogical that the mc kept roaming around when he is at the bottom of the food chain but I guess it was necessary to move the plot.
