Um Jammer Lammy builds on a lot the first game did, fixes a few problems like the weird stiff animations that feel delayed, but it misses the mark by continuing issues from the first game, like having really delayed inputs and a judge that makes no fucking sense.

Like, the only way you're going to even dream of getting a positive result from your notes is if you do them before they end up flashing, it's really weird and I don't understand how this survived all the way up until the second game where the judge and controls are all perfectly fine.

Past that the tracks are pretty neat, minus the sixth stage where it's brutally hard (YOU SHOULD BE BANNED FROM EVERY GAME) and that's all fine and dandy, and the extra Parappa mode is cool, but the versus mode is really crap, if you want to play versus just play the second game.

The cutscenes range from just confusing and weird to confusing and hilarious though, I don't know what they were thinking but they clearly toned it back down for the second game.

I do recommend it a play, with most of the series being very fun rhythm games even putting aside their frustrating difficulty in the first 2, fun times.
