I ran into a bug while encountering Cathy where the text GotoContinueButton;;;CanneleRageMania appears on screen and there doesn't seem to be a way to progress past that point. I'm playing on Linux, if that makes a difference.
Another (but not game breaking) bug I ran into was an error in the Hee Cup scene complaining about $victory = true using an assignment operator instead of an equality operator.
Otherwise, I've been really enjoying the game, it's unreasonably good and the conspiracy board in particular is great for making you feel like you're piecing together the solution to some large overarching mystery.
