It was going well until he said "program"... there has been no indication at all that he has been isekai'd... and other than the appraisal crystal, there's been no magic tools shown at all. So where the hell did "program" come from???
Plus he hasn't even used the Loop feature yet, but he already knows exactly what it does and starts celebrating.
I was really interested in this story until that last page. Now I'm just worried it's going to be full of these kinds of inconsistencies.
