Meh. Felt kind of flat, and not funny, although it clearly was trying to be. Essentially another one of those isekais with "it's not a skill, but how you use it" theme, but instead of just 1 "lame" skill there are multiple ones, which are not clearly defined, but which become extremely useful right away. They do not seem to make the guy overpowered or anything, but they still make his life too much of a breeze right away, especially since he was able to kill lvl8 mobs while being lvl1 (and a bit later lvl2).
I think even Slime was not that fast and powerful in 1st episode, and even if he was, I feel like he was gradually accumulating skills through actions. In this show, some skills do get added through "special use", but it still feels a bit forced, at least because they were added after 1 use, apparently. The MC is also just boring to me. His main trait is that he wants to be alone, I guess (early in the episode I could swear he was summoning Bocchi-san). I mean, the fact that I am not even interested to see how he becomes a girl-magnet says a lot.
