I don't trust overly negative or overly positive reviews, so I'm going to lay it out both good and bad. Also gonna try not to reveal too much in the spoiler territory.
First, this is another top tier game. It's well written. The characters are more believable than most. It's an interesting story. Action sequences are well designed (especially for this type of game). The story pacing is pretty damn good, we're given good chunks of story, character reveal, and lewd. I'm invested in the story and characters enough to look forward to what happens next.
I do have some small problems. I mean, some things about the MC and why he does what he does are explained a bit later in the story. However, I think there needs to be more emphasis on *why* the MC doesn't really explore his new magic right off the bat... again this is sorta explained later... but we need more hints of this at the beginning. Looking at comments, dev, you're losing people before they get far enough into find out what's going on in his head. Also, the reason the MC is respected by so many of this new society is... a bit lacking. I can buy folks respecting his restraint in using the new powers, that merits more respect than the... story elements involving his courier job.
Why would one of the ladies think the MC is gay? This needs to be explored a bit more. He obviously checks out the ladies, the male gaze exists. Women notice. So this needs to be explored more.
MC's depression is a bit too much on slow-reveal. We need a bit more inner monologue on this, need to feel it a bit more at the beginning as we go through his journey. He doesn't have to be a totally mopey nerd, but it feels like the story forgets about this for a bit then comes back to it so it's slightly out of place.
Also there is my pet peeve. Convenient bisexuals. Let's please stop shoe-horning girl on girl action in with the convenient bisexuals. It's an over-used story element. Especially in a game that works hard on the characters. With two of the possible harem candidates, MC also feels a bit like a third wheel after-thought.
My initial positivity for the game stands, despite the flaws. It's easily in my top 10, if not top 5.
