Yep. It takes a certain amount of skill to be able to ramp up the power and abilities of your protagonist without the story getting away from you.  That’s kind of why I described what I could recommend as series because there’s a few where the first few work well HWFWM being one of them but after that, there’s a pretty significant drop off in quality of the overall narrative.
And even one of those that I’d say that I recommend (Ready Player One/Two) works pretty well but more so for a subset of readers that I just happen to be part of (those whose main cultural media experiences were between the 70s and the 90s.) and while the series works moderately well it’s definitely written to a specific subset of readers.
As an aside because I already mentioned two of the three I recommended in the original comment, I should probably also recognize the third just for posterity. It’s the four book trilogy, This Trilogy is Broken by JP Valentine.
It’s mostly fine… It kind of suffers similar flaws to the second Hunger Games book by being a “let’s do that again”-style rehash of the first. But the series makes a cohesive whole.
I think one of the reasons Broken works fairly well for me is it doesn’t feel the need to tie off every loose thread by the end. I still end up wanting to return to the world without the story being anti-climactic.
