The twist behind this game are the color notes where the player has to switch the background color to match the note color. These switches are on the left and right side of the screen where the player has to alternate between red, blue, green, and yellow. Not matching the note color will result in color GREAT score compared to a PERFECT score.
Great game to get into. UI is a bit outdated and option settings are in Japanese, but looking forward to see future updates.
