Artwork is good, but the detestable main character, 'plot', and 'gameplay' activities all need to be thrown into the garbage, set on fire, razed to the ground, and started all over again from scratch.
When I first played through the prologue I thought that I had given wrong answers to house riddles and the prefect introduction scene, that as punishment the game had trapped me in the office with nothing to do.
I looked up a guide (don't bother attempting to figure this insane game out) and found out that this is not intended as a punishment, being trapped in the office with nothing to do is just the game.
Instead of a game where you can walk around the school locations as you wish and chat with characters, you have to send mail, wait for a character to show up, ask them one question before they leave, then skip time to the evening and skip to next day to write more mail to that same character again so you can be escorted under guard to an empty room where if you accidentally click the wrong thing you will be forced back to the office to try to attempt a single 10 minute task across all day tomorrow.
TLDR this is a prison pen-pal simulator.
