Okay, so I played through the whole game, and I could only ever get the ending where I fail to solve the mystery (either that, or I'm softlocked). Some bugs I encountered:
- When I go to talk to someone on Days 3-5 (in either the Alley or the Church), I get met with a brief flash of a woman before the game immediately exits out of the dialogue screen, with no ability to converse with her. On a similar note, it's possible to end up with a negative number of action points in places like the alley. Once you hit this stage, the game traps you in this area and you can't leave.
- When trying to uncover the culprit on the final day, I get told that I still need to uncover more evidence, but the game won't let me leave after midnight, so I'm just softlocked in the final portion. Due to the lack of save slots, I cannot revert to a previous save and have to start a new game.
Maybe it's different in the downloadable version (this is all in the browser version), but these are all the bugs I could remember. Also, can't select settings or the credits menu.
