Visually, this is an incredible tour de force. It's bright, colourful, sharp, and appealing. It just pops. Even the menu has neat looking train tickets and spiffy animations. I haven't played every game in the jam, so I can't say for sure that it's the most impressive in the jam. But it's definitely a contender.
The title text in the main menu is a bit crunchy. But that's only really apparent because everything else looks so good.
The soundtrack and sound effects don't come to the forefront as much, but they're still very nice and work very well.
I know Song of Morus are meant to be hard/intense games, but even still, this is a step up on the difficulty curve. It's one of the most disorienting games I've ever played. The narrow field of view means you can barely see anything else while aiming at the enemy, bullets come from behind you with no warning (at least, none that I could see or hear), and moving around the train snaps your view ninety degrees over.
The tutorial mentions a wooden sword, but I couldn't figure out how to use it.
I'm sure there are people who can play this, but I'm definitely not in that group. It didn't make me sick or give me severe eyestrain, but if it were longer it might have. Once again, I know what you're going for here, but part of me would really like to see a more accessible Song of Morus game in a similar style.
It's always neat to see Chinese mythology and Hong Kong culture in these games. Some of the dialogue is a bit stilted and could use copy editing, but that feels like a minor complaint.
