This game is free. If you're a fan of Sonic and the Sonic universe, that's all you need to know. It's a train murder mystery adventure including Sonic and the gang, and you (a new employee for Mirage Express) work alongside detective Tails to unravel the mystery of who murdered Sonic. It's a unique setting for all these characters to find themselves in, and for what it is, it provides a fun two to three hours for Sonic fans.

If you're not a Sonic fan, and especially someone who (almost) never plays Sonic games, there won't be a point to playing this, as you won't know the characters and most of the charm of this game will probably be lost on you. I myself have played the first few Sonic games ever released within the past 12 months, so I know many, but not all of the characters that feature here, and I did feel like I'd get more enjoyment out of it if I were a more avid Sonic gamer.

That said, I did enjoy the game. The game plays itself for the most part a la visual novel, but interrogations include mini games in which you control Sonic from an isometric perspective as he collects enough rings to beat a level, which allows you to formulate an argument. Simple, but challenging enough. Just don't expect more from this game than it is, since it is free like I mentioned. If a gaming franchise I really like made a similar project like this, I'd definitely be really excited about it, and I think it's really nice that this exists.
