[History]
2019/11/27 Ver 12 released
-Fixed a bug in CASE 2 that caused some investigation procedures to fail to progress.

-A bug was reported in CASE 4 where the menu screen could not be opened in the event of tracking down a fugitive criminal, making it impossible to progress.
Since the cause of the bug is unknown, we have created an alternate route where the game progresses by talking to the character in the lower left corner of the screen when the bug occurs.

-Other typos, display errors, and inconsistencies have been fixed.

Ver 11 released on 11/22/2019
-Fixed a bug in CASE 3 where entering Assistant Professor Mizuno’s room without a specific piece of evidence would prevent you from moving around the map, making it impossible to progress.
If you’ve already lost progress, you can fix it by moving from the down stairs on the left side of the corridor map.

-Fixed a bug in CASE 2 that prevented the control character from being displayed if you proceeded through the choices in a certain order during the first verification.
If you have already encountered this bug, please continue with the game and it will be fixed automatically.

-Other typos and display errors have been fixed.
