Wow, you really deserve a 10 for this review, I'm very happy to see a sincere review like yours, explaining the facts and enrendo in general, thank you very much indeed. As you mentioned, I really don't think it's very interesting for an MC to dominate for the time being, maybe after a traumatic event he'll become more cruel, but I think it's very silly for a person to totally change their personality from one month to the next because they've gained power, it has to be done slowly. The villains and characters are really going to be changed a bit, this story is based on horror but it's a bit difficult to create an atmosphere of horror and tension when the protagonist has super powers, it ends up becoming an action fight, if you have any advice on this I'm open.

As you said, creating the same tension and teeth clenching excitement typical of a horror genre would be difficult as the abilities of the protagonist inevitably goes up. This is simply the natural progression and evolution of a character that has been gifted with a game changing ‘cheat’ like the system and its an unfortunate plot killing point that few authors ever truly handle correctly… While there are a few fast solutions to handle this fluctuation in strength, like scaling up the enemy’s strength or nerfing the protagonist, such ill thought shortcuts are essentially poisoning the story as it chips away at its integrity from the core. I don’t like it when the author paints a beautiful picture only to go back and coat the picture in a dull finish 🫤 okay, bad analogy, it’s more like going for fast food and using the picture on the menu to make your order but the product delivered is subpar… but it’s still better that the character is nerfed than seen too incompetent. What is more detrimental to the character design than receiving an ability that should skyrocket him into the peak of life yet he remains middling at best and his waking hours are spent constantly running in fear like a fugitive? Do note that this isn’t always a fatal flaw. A strikingly successful example of this can be seen in DBZ, where it holds quite the cult following despite the obviously inconsistent measuring of power levels in fights not making any sense ( jumping from a few hundred points being capable of destroying the moon, to power levels in the millions-trillions doing combat without accidentally destroying the planet). Personally, if it was me writing this story 🤔 I would probably drop the very notion of the story feeling like a horror story and make it more of an homage to horror or just an outright spoof 😅 but seeing as that doesn’t seem to be your intention… I agree that the best matches to spectate are the ones between forces of similar strength and ability. You could make it so that his ‘world travels’ are more of a trial and his powers would thereby be restricted to within the realm of that world. He could essentially become a stand in for the MC of that story… but doing this would also leave the character open to a greater degree of risk. I doubt you would grant him immortality 😮‍💨 but if you want to persuade him to take the risk to venture into those circumstances you’re either going to need to sweeten the pot (which means he becomes OP upon success 😓) or threaten him. 🤔I guess he could activate the system transfer the next time he’s getting beaten into submission by that sadistic demon… 🤷🏻‍♂️ If you do go the path of nerfing the MC I would suggest you moderate the system itself (rather than the protagonist), making sure that every shackle you place on his powers are necessary (or use enough sophistry to sell it) and never remove the promise of eventually breaking those limitations… after all, it’s within our nature to seek out perfection 🫤 and with a system as guide, anything less is a tragedy. The most important aspect I will give you in the story and one I truly hope you appreciate… make the story that YOU want to read. Make it something ENJOYABLE to write. Have FUN designing the fate of your protagonist and 🤨 think of the protagonist as the vessel of your next life. Any fate that falls upon him will be your boon or burden to carry… let him live the life that you would hope to achieve and be a person deserving of your respect. Well…… I tried my best in giving you some feedback.
