Fun for casual ,used gamers of many levels

O2 Jam U has proven to me that music mobile gaming can be very enjoyable, and being a long term veteran of music gaming (DDR, IIDX, Stepmania, Guitar Hero, ect), this game is a great addition to any tablet. While most of the songs don't prove to be difficult and require only a few attempts to pass for experts, novice to intermediate level players will get a very high amount of progressive scaling difficulty, a wide variety of songs to pick from, and multiple keys to progress from.

The major downside to this game is that it really has only been enjoyable for me to play on iPad, and even on the 6+ the buttons feel too cramped. Alongside the lack of difficult songs, it only brings so much to the table at the end game.

Fun, but needs to be updated

It’s an amazing game and I’ve had tons of fun with it over the past year or so of playing, but sadly, it doesn’t work anymore. After updating to iOS 11, it won’t open. I really truly hope that the developers come back just long enough to fix it so it’ll function.

Finger fun

I am an avid DDR player, but those are all Japanese songs. Since I am learning Korean and will go back to Korea I was happy to find a game that has Koran songs. Though my wrist are screaming at me already for playing so many times I am finding this quite enjoyable. You did a wonderful job.
