Gaikotsu Kishi-sama, Tadaima Isekai e Odekakechuu was originally an 8-volume series that ended up being continued roughly a year later. Personally, I’m content with that original slightly open-ended conclusion and won’t be following it any further.
The books are at their core a pretty standard overpowered protagonist isekai, which isn’t an inherently bad thing, with a couple noteworthy traits (the oddly subdued romance and lack of any harem elements being the main ones). The characters are all pretty likable and it does a great job with the pacing, a particularly laudable accomplishment considering the barely acceptable pagecount.
Issues would be the noted small size of most of the volumes (based on the second Afterword, the author is apparently one of those who feels readers are inconvenienced by having more to read), the spontaneous cooking subfocus that pops up in the fifth and sixth novels, and the persistent use of the term ‘wagging’ to describe the catgirl’s tail movement (which may just be a translation issue). Although I guess you could also consider the lack of direct romantic development a problem as well.
