This was a fun treat, much more charming and considered in style, polish, writing than I expected from a free April Fool's surprise, with a framing that lets each character's personality shine a bit more than they often get the chance to in the mainline Sonic series.
Think it was smart to serialize the story via a linear progression of train cars, too, given the intended audience is Sonic fans more than the sort of die-hard mystery VN fans who might want more freedom in the investigations.
My biggest complaint is the over-reliance on a minigame that feels like it's there to placate fans who demand some form of action in a Sonic game and is asked to prop up a climax that might have been better served by more of the sleuthing and lite-deduction that's more core to the game.
