more I wish you could still play in portrait mode rather than strictly landscape. I also don’t like how the songs are locked behind a subscription paywall now instead of using coins to play songs. I still love this game though. I used to play it a lot many years ago.

Honestly, I can’t understand why O2jam company developed this new app to replace the previous one. Although the new UI design may look fancy, but actually the experience is not as good as the previous version. The quality of music is another thing that doesn’t make sense. Songs just don’t play in a normal sound effects. It is ironic that the most nature music is the background music.I’ve been playing this game for more than 5 years and I’m really happy to see it back to IOS platform. But please, don’t disappoint the fans. They love this game!

I love o2jam the original on pc, was just looking for old games than i saw i could get on ipad, ok is a little too much charge for the base game and then for the subscription to have access of all songs, it would be better if was free and with like package 1 and 2 and subscription for the songs, other thing is that you should add a keyboard support, now with the ipads pro and to many things making people buy a keyboard case, this game would be 5star for me if it had a keyboard support

I loved o2jam and o2jam u. This app has a lot of potential with a few fixes.First certain song charts aren’t synced to the music such as heart beating and the love. This diminishes from the experience.Second the song titles don’t have music previews so you can’t tell what the song will be likeFinally the game needs a harder judgement setting so it is harder to play notes perfectly almost all the time.Once those are fixed the game will definitely deserve 5 stars.What is great so far is the offline play, the music, and the price of the subscription which is totally worth it once the game gets slightly modified and fixed.Good luck and keep up the good work.
