This game improves everything that the prior game had. There are now cooperative and versus modes, replays, alternate songs for Parappa, and other things. The button inputs at the top still don't match with the timing, but it's not as bad as before... I didn't find out until Parappa's music that there is an easy mode.
The textures for this game are more detailed (Think of typical PS1 and N64 games), which I thought didn't benefit Rodney Greenblat's simplistic art style the characters have.
It was very fun! I love the characters and world. You have to make a lot of mistakes before understanding the timing for each song, but the vibes makes it bearable and worth trying.
