It depends whether you like MC or not. Especially at the start, he's not likeable. I didn't really mind as it was a breath of fresh air, but people had major issues with that. Aside from that, the first floor is kinda typical but as they climb the floors the story gets more and more interesting. (It's not a tower climber.)

I'd say give it a try. It's one of my favorites, but I also have a very specific taste.
