If Parappa the Rapper is a low-level drug trip groove through an increasingly weird week, then Um Jammer Lammy is the ecstasy-laced fever dream weekend. The story follows Lammy trying to get to her band's gig on time but constantly running into characters who insist she helps them with their high-stress jobs. Things move at such a frantic pace that it's difficult to have any idea what's going on. Characters are constantly yelling, cutscenes have 5 edits every second, and, unlike Parappa's story beats, Lammy's hurdles are completely random and unrelated to her personally, so it's just a blur of complete chaos. Unfortunately, that carries into the gameplay itself.

Lammy's music is seemingly written to be intentionally confusing. Nearly every song is plagued by bizarre time signatures, button prompts that don't match the cadence of the lyrics, and segments that require a level of speed and button-mashing that Parappa never came close to. This game also amplifies a problem in the first game: the small delay between pressing a button and the audio of Lammy's guitar actually playing makes it absolutely impossible to keep time consistently. Most levels feel like they're won with dumb luck, especially Level 6 that features an atonal, arhythmic stage aria. Most times failure comes at the very last moment of a song, forcing you to start from the top and struggling against the game's design again and again.

Um Jammer Lammy feels like it learned all the wrong lessons from Parappa, which already had its own issues. Chaotic in every way, from story to gameplay, Lammy frustrates and annoys with each new riff screamed at you by another anthropomorphic psychopath. Much like Lammy's guitar, this game is out of tune.
