There are indeed. 'Overlord' can also be considered in a way. The main character has a leveling system within the game - like world he is in, and his power progression through that system is a key part of the story. There are also many other light novels in the isekai genre that feature crazy leveling systems and have gained a large following.
I'm not sure specifically as there could be many novels with a 'crazy levelling system'. Generally, it might be about a unique and perhaps out - of - the - ordinary system for characters to gain levels, power, and progress in the story's world.
Well, the 'solo levelling novel' tells the tale of an underdog. In this world, hunters are tasked with protecting humanity from the threats that come out of these mysterious gates. Our main character was once a very weak hunter. But he discovers a unique ability that allows him to gain power at an extraordinary rate. As he levels up solo, without relying much on a team, he has to deal with not only the physical threats of the monsters but also the envy and suspicion of other hunters. His story is one of growth, self - discovery, and the pursuit of true strength in a dangerous world filled with both magic and mayhem.

I'm not sure exactly as I haven't read it fully. But generally, it might be about a character's journey of leveling up in a world related to gods. Maybe the protagonist has to gain power, face challenges, and interact with divine beings while on this leveling - up path.
Well, from what I've heard, in 'levelling up with the gods novel', the protagonist starts from a low level in a world full of divine powers. He or she has to go through various quests and battles, learning new skills and magic along the way, all with the ultimate goal of reaching the level of the gods. There could be different factions, some helping the protagonist and some trying to stop him or her.
