Beatmania IIDX---week 3

Primary Gameplay Mode + Core mechanic

IIDX is a music simulation game that is both very simple and very hard at the same time. The game interface is mimicking DJ turntable and a set of keyboard. There will be notes dropping from top of the screen as music plays, and players must press the key when the notes reach the red line or they get a poor.
IIDX provide players several play modes for mean of challenge or sometimes assistance.
--Auto-key
--Random/Mirror
--Hidden/Sudden
--Hard/Easy
--Speed up/down
On top of these modes, players are able to choose to play songs in Normal/Hyper/Another, where difficulty can jump 2 folds.

Not much twist or manipulation in this game. But IIDX offers training exercise on both finger dexterity and mind reflex, which dynamic elements are placed.
