This is an actually good serious.
The MC has a 'Cheat', sure, but it doesn't Cheap the story telling. This isn't just a constant lvl up fest where he beats any and all opposition, the occasional antagonist does get a leg up on him, he doesn't have infinite power ups to pull out his ass and one up people. The situations he finds himself in can be adequately challenging, sometimes requiring him to back off and rethink his approach. Though the beginning is pretty easy, but it's more like an introductory difficulty.
