Love Lab/Unused

Rhythm Heaven
Love Lab consists of the following versions in Rhythm Heaven:

Unused Content
The Mysterious Lab Tech has a full sprite, but most of it remains off-screen.

An unused version of the Try Again epilogue exists, where the characters' lab coats are drawn more consistently with their in-game appearance.

Regional Differences
The prologue in Rhythm Tengoku Gold is animated with an 相合傘 (Ai Ai Gasa), which is the act of sharing an umbrella with another as a romantic gesture. The International version is static, and has a pink and blue abstract font. The title also moves in a very choppy way to the center.
