After playing for two days, I've completed the first chapter of the story.
In Deemo 2, there is a friendly reminder before we start talking about all aspects of the game. For example: when I use my wireless earphones, it reminds me that there will be lags, and turning on the calibrate will simply work.
When you press play for the first time, you will instantly enter the game's world and start playing after watching an animated sequence. At this point, there are no typical tutorials (though there are some), but a very clean layout, ethereal backgrounds, and simple beats. Without saying anything, the game will directly present the song to you and you can play the game. Upon reach to the climax, the game will immediately return you back to the animation, the station master is playing the piano. Such a transition is amazing.
That's everything for now. Start a new game?
