Who miss this game? It is really fun and tough old piano like game that tests your speed and accuracy. You may customize your character to add come cool stuffs which can be purchase online. This game bloomed in my early elementary days but I only experience gaming this when I was in high school year back 2009. It was so much fun, at first of gaming you'll experience dizziness or somewhat waving images on your surroundings after a couple of songs played. hahaha..
I had also experienced playing this on a private server if I'm not mistaken it was O2jam International I think. Though this game was already faced out through years, yet you may still play the online version, the O2Mania. Song packs can be download anywhere you'll just have to browse it to see.
This somewhat saw that this game is also now in android and Ive gotta check it out later to see how does it look like and works. Hoping its gonna be the same as what we have experienced from those old days.
