Level Up!: Press Start Kindle Edition by Simon Archer
In a world full of super heroes, be a power gamer.
Everyone has a super power, even Sam. The thing is, Sam has a power unlike anyone else. He can level up.
That might not seem like much, but when everything from doing dishes to thwarting robberies gains you experience, Sam has finally found a way to become the most powerful hero the world has ever seen.
And it’s a good thing too because the world’s most powerful villain has come back from beyond the grave, and if death didn't stop him, what can anyone else do to stop him?
And Sam? Well, he doesn’t stand a chance right now, either, but if he can level up just a bit more… anything is possible.
Warning: This book contains awesome super powers, sexy women, sex scenes, explosions, crazy power leveling, and the ability to become the strongest person the universe has ever seen. That’s right, we said universe.
As the author of the books you linked I'd love it if this were the case!
However, there are a few different books with very similar titles.
The exclamation mark suggests maybe it is this one? https://www.amazon.com/dp/B08G132ZRW
Or it could be the Level Up series? https://www.amazon.com/dp/B07CKRMLJB
Level Up series by Simon Archer might be up your alley. I stopped at the 4th book, but it looks like he put out seven of them.
