The player character has one hell of a response to getting his arm ripped off, "ahaaa, I see you wish to play a mind game!".
Your freezing ending issue has NOT been solved btw. I stopped counting after five, it even froze up after I was CERTAIN that I won as the killer started glowing after I shot them and then...nothing.
Also I gotta say the killer was pretty obvious, I picked them first and assumed i'd get the bad ending because I was guessing the real killer would have been pinned down by some easy to miss clue(rather than being told outright who it is just before making the decision, he was my first suspect before that but I assumed it being stated in dialogue would make them the easy "gotcha" ending)
Also I think it would have helped confuse the player if 1)Maxwell had been a suspect at the end, he was actually my second guess due to his closer proximity to each victim and 2) if the big glowing targets didn't show up on each person you aim at. It clues you in that even the dead are potentially proxy.
I really did like the concept though, but the execution wasn't great. An option to skip to the end would be a huge save after having it crash so many times, and more annoying is the game auto pauses when you try to click away to a different tab so you can't just read something until you get to the final choice.
A big criticism I have is the dialogue, it's very clunky and unnatural.
More distinct sprites and voice acting would make things better, but wouldn't be necessary.
Some small animations might help too, even just people turning to one another.
Even after all this I still hope you don't get discouraged from making more games in future, I think your imagination works well and with a more critical eye you could make some really good content in future.
Good luck, you.
