This has a overall pretty weak songlist and I like the gameplay in Project Diva f2nd better, but I really have to praise the UI experience they created here.

There's tons of little QoL touches everywhere that make playing the game a more pleasant experience, like the song grid, countdown back to the song you're playing if you pause, how quick you can seamlessly switch from the main menu to the song list and from it to a song (loading screens are really fast compared to the vita PD games and even steam PDMM+), a daily play function and so on. Overall, the UI is just really beautiful and stylish and puts PDMM+ to shame.
