*Inputting the code word {{Nihongo|POSITIVE}} in [[Police Call]] gives the player a tip about there being a code word in this game (the word is {{Nihongo|MATCH}}: every 130 steps Mr. Upbeat's antenna grows larger and displays the word one letter at a time, then returns to normal). The code word can be put into [[Police Call]] for an easter egg.

The player controls a mysterious little guy named Mr. Upbeat, who must step over a metronome needle to the offbeat of the song. As the game starts, a voice counts off a rhythm for eight beats. After this, the needle begins to swing at Mr. Upbeat. To dodge it, the player needs to hop over the needle, which happens on the offbeats. To assist the player, the light on Mr. Upbeat's head flashes on the offbeat. After 16 steps, the needle stops. The player recieves a point, the tempo increases, and the game repeats.
In Rhythm Heaven Fever, each step gives a point instead of one point for every 16 steps. In addition, the tempo change happens every 32 steps rather than every 16.
Miss...?: Mr. Upbeat trips on the needle, and the game is over. Depending on which side he trips from, he either falls on his bottom or spreads his legs. Usually Mr. Upbeat slumps in defeat, but if the player got a High Score, he pumps his fists at the achievement instead.
Mr. Upbeat does not appear in Minna no Rhythm Tengoku. The game Manzai was substituted with Mr. Upbeat due to the Japanese-dialogue focused nature of the game[2].
Manzai was the 4th game in Minna no Rhythm Tengoku, while Mr. Upbeat is the 1st in other regions. This change caused the rest of the Endless Games to be moved around in other regions, and their Medal requirements to be adjusted.
