진짜 너무 좋네요

정말 어릴때 컴퓨터 오투잼을 해온 유저로써 너무 반갑네요 ㅠㅠ 다들 싱크가 안맞다고 하는데 전 싱크도 다 잘 맞고 시스템도 깔끔하니 좋고 업데이트도 꾸준히 되어서 좋습니다 ㅎㅎ 잘하지는 못하지만 꾸준히 다시 오투잼앱을 이용할 거 같네요 감사합니다!

please

Come on, I’m glad u guys back. But delete the network connection at the beginning during every game. I always play it offline on the plane. Now I can’t play it until the network loading is failed in every game. This is ridiculous.

Hello, and thank you for getting in touch. We sincerely apologise for the inconvenience you’ve experienced. A few other users have also reported similar symptoms, but unfortunately, we’ve been unable to reproduce the issue on our own devices, which has made troubleshooting quite difficult. If possible, we would really appreciate it if you could let us know your device model, and if you’re able, please record a short video of the issue and send it to us at help@o2jam.com. Also, before doing that, could you kindly try completely deleting the app and reinstalling it? If the problem still persists afterwards, please let us know in your email.

앱 실행 안됨

게임 화면 방향을 오른쪽으로 설정하게 되면 처음 터치하는 화면에서 실행이 안되고 앱이 계속 꺼집니다 그럴때마다 삭제하고 다시 설치해서 사용할 수도 없고.. 문제 해결 가능할까요? 월 구독하고 이용하는데 너무 불편합니다 (아이패드 프로 4세대 사용중입니다)

The game crash

I’m using an iPhone 15 pro max and the game crash when I launch a song. It goes until 99% then crash. I tried to uninstall and reinstall the app and clear the cache, same issue. Too bad I wanted to play this game as I used to play it on PC in 2006

Please make vertical version

I don’t understand why the developers can’t make a vertical version for iOS.. Android users have a vertical version and tbh it shouldn’t be that hard to make… and it’s been years;; my 2 thumbs can’t reach the middle space button at all and I miss half of them cause they’re too far.. please please please please please please please please please please please please make a vertical version. I would play and subscribe if I had a vertical version

Response from developer

Creating a vertical version can be tricky to develop depending on the original design intention. We understand that there are many inconveniences as the size of the phone gets bigger. We will improve these points in future updates. If you want a vertical game, we also have a game called O2Jam - Cats developed with our music, so we recommend you download and play it.

今回のアップデート

新曲の難易度がどれもおかしいので修正してほしい。レベル15ほどなのにレベル35と表記されている。難しくて手応えのある譜面なのかと期待してしまった。
それと、O2JAM Uに収録されていたAdditionをまたプレイしたい。

Can’t touch 4 fingers on the screen at the same time!

Did the developer give up this app? I can’t touch 4 fingers on the screen at the same time on iPhone 15PM, resulting in frequently breaking my combo, bad experience!

Since the game is primarily designed in landscape mode, that issue can happen. We’ll keep working to make the experience better. If you have any good ideas, please let us know! We’re always listening at help@o2jam.com or through https://rank.o2jam.com. 😊

The game is dead

How to explain? The Game does start, yepp. The Game has a working UI… but the sounds won‘t appear. So I can‘t play the game. The play is unplayable…

Hi! We’re really sorry for the inconvenience. 🙏 First, please make sure your device is not in silent mode. Also, try fully closing and restarting the app, or reinstalling it. If the issue continues, please email us at help@o2jam.com with your device model, OS version, and a brief description of when the problem occurs. We’ll check it right away. Thank you!

I love this game

One of the most entertaining rhythm music games I’ve played. I haven’t been able to find a similar mobile app like this one. The songs are refreshing, and you can gradually learn them to face higher difficulties. I love this game.

I used to play this more than 10 years ago! Then all of a sudden the app stopped working and vanished from the app store.
I didn’t know you’ve been back since 2020. Thank you for coming back! I am so happy to finally play [Invitation] once more. It’s an easy song but it’s so relaxing and fun.

Please don’t go away again 🥲 I look forward to exploring more O2Jam songs

This game brings back my childhood but can we get an update from this game? It hasn’t been updated for awhile. A lot of people still plays this game including people with subscriptions. Thanks

I Miss Vertical Mode

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.
