Sorry to hear the game disappointed you. ^__^; This was my first attempt at a mystery genre game. To address some of your criticisms:
1: For times when you object to truthful statements, I don't recall any of them off the top of my head. I do have autism, so it *may* be a case where my interpretation of a sentence differs from average people. So if you can elaborate on which lines this happens on I can try to fix them.
2: Regarding the amount of MC content, I did find it difficult to arrange extra mind control without it interfering with the pacing of the mystery. This may be an issue with my inexperience with the mystery genre. I tried to include a few extra instances of mind control beyond the trials though, such as Anne getting possessed and Olivia being charmed.
3: What kind of buggy navigation did you have? I can try to work on fixing any issues you've found.
4: Villain mode does break the established norms of trials, but my thinking there was that playing as the villain, your goals are different from the investigators. So, you wouldn't be playing exactly like the investigators.
5: Miranda mode has more than just the one new CG at the end. There are four new CGs throughout her version of the story in addition to the ending. You mentioned clicking through it so its possible you missed them?
I can't make any radical changes to the story, such as adding new scenes at this point, but I am definitely open to fixing any bugs or logic errors that I may have made due to being just one person. Thanks for the feedback, I hope you are willing to elaborate on the issues that need to be fixed so I can look into them.
