One other problem is just how many mistakes the MC makes allllll the time. For example, the unique skills (sacrafices). By the time he unlocked being able to upgrade the skills, he still had many, if not all of, his skill points. As we noted with his mini-map skill, the unpleasant side effects of the skills have the possibility of being removed with more level-ups. With that in mind, would it not be worth the risk to instead invest in an over-powered skill like the one mentioned earlier in the novel with the ability of a god within a certain area but being trapped for eternity. If he could invest all of the skill points he earns afterwards in the skill, wouldn't it be possible to be invincible?
The point is, this MC just makes too many mistakes and its kind of frustrating him walking around all cheerily when hes doind stupid sh*t all the time.
Also, side note, with such a care-free character, throwing in serious moments like when talking about his fiance with "World" is just awkward and throws off the pace.
