In all fairness, this VN looked great, but everything else was a pure disaster. The plot, which absolutely didn't know what it wanted to tell (a teacher at a girls' school or a kinetic novel about a guy with a massive inferiority complex in a mafia story who is taken out of the plot in his own story or about a guy who can't get it up with his wife for reasons). Or the numerous spelling mistakes, I mean you don't have to be a native speaker, but couldn't you write the dialogues in a program with a spell checker, then translate them via (good) translation software (not google translate)?
This VN may have been successful in the V part, but the N part was an absolute disaster. One could have saved themselves the trouble and made a comic out of it, or an animation.
In principle, it is reminiscent of the failures of recent years, such as The Day Before, where developers overestimated their own skills and underestimated the effort involved. I don't want to badmouth Betisis, but from what I see, someone like him should only work with people in a team and only when he is as far away from the plot planning as possible. You can use him to design renders and possibly animations, but for everything concerning the plot you should only consult him when it comes to "Is scene xyz possible as a render or not and do we have to rewrite it?"
