Should make a manga like "Help! I'm stuck in a badly written otome game!". People who didn't actually appear in the game are more or less normal, but any game characters are stuck with expositionary dialog and/or monologues, wooden acting and wildly inconsistent personalities, and those without lines are more or less cardboard cutouts. The MC mainly just tries whatever she can think up to escape the plot but keeps getting pulled back in. She played the game only briefly before getting isekai'd, having thrown the game in the trash after stubbornly completing one wholly unsatisfying good end.
The game was known for it widely branching storyline and many possible endings, advertising almost 10000 hours of gameplay in total, but it's all terrible.
