This work doesn't merely share themes with The World God Only Knows, it borders on copyright infringement.
I would totally support an almost rewrite of an existing series if the author culd present and execute those same ideas in a superior way, but this piece falls short.
The primary concept, i.e. an analysis or parody of dating sims, is executed poorly.
Despite the notable flaws of TWGOK (I would rate it a 6/10), it effectively navigates its chosen mechanic, as one would expect from an author who decided to build a story around it since has something meaningful to convey.
In contrast, this narrative is disorganized and unfocused.
The main character is basically an OP Keima who one shot heroines like Saitama through absurdly simplistic interactions. Each of these encounters feels like a direct lift from TWGOK, yet they are way more cringe.
TLDR I think this is very bad.
