I'm a bit surprised to find this isn't dumb comfort-food. Though I'm not sure what it is instead, yet.
So far it's an interesting mash-up of different genres and the tropes that go with them (and I'm not even sure it's done adding to them). Particularly, the scenes in the "game's" world and the scenes in the "real" world seem to be adhering somewhat to different genre conventions. Endo and Kobayashi's relationship feels like something plucked from some of the classier breeds of seinen romance. Meanwhile Liselotte is fulfilling the isekai-ish comedic sympathetic shoujo villainess-role to a T and that setting is going through the trials and tribulations of game-plot-run-amok that we've come to expect...
And unlike everything else in the latter genre, it sort of looks like what the heck is going on (why game characters are "living" an autonomous real life in their own world) is actually going to be an up-front-and-center element of the plot.
