可以支援 7keys 的音樂太少了,完全沒有回到以前 O2.Jam online 那種感覺
回来了,但又没回来。
3 months, slow progress, few songs, SELECTED 7 KEYS MUSIC, then *BAM!* DLC goes out This is the biggest mistake i ever did, to believe them bring back the old o2jam
i've played this game since the very beginning. have played so many versions of it. i have to say this is the ♥♥♥♥♥♥♥♥♥ version out of all. just dont waste your money lol the browser version was doing just fine
オリジナル版の頃から遊んでいました。その後とても不評だったバージョンも遊び(個人的にはシステムの面では悪くはなかったと思ったが・・・)、現在はこちらの新リリースを試すことにしました。 オリジナル版の曲を一通りプレイしてみましたが、360Hzのディスプレイを使っても特に設定をいじらなくても同期の問題や音ずれなどはなかったですね。 UIはもっと画面を広く使ってもいいと思いました。(縦スクロールにして、それぞれの曲の全難易度が表示されるようにしたりとか) まだリリースしたばかりなので曲数も少ないですが、個人的には以前のオリジナル曲がもっと復活してほしいですね!(Gaussian Blurとか^^;)
장점 2d모드 나와서 할만해졌다 용량이 적다 단점 7key 곡 부재 7key 곡 추가해야함
Pros: Nostalgic with 2D view I like how Devs are reviewing user's comments and feedbacks. Got a discount on game to try. Cons: Not a lot of songs are out yet, was looking for classicals/Kan Kan etc. I'm not sure but the notes aren't really insync with the music. (Could be a me problem) No customization? I played on 2D but i think the customization was only for 3D. Overall I believe they're still in early stage. Maybe I'll come back again when they have more songs updated/purchased.

Hi iam Nie iam so happy and grateful for the awesomeness and special gift everyone sweetness shown in me so so cool and unique individuals wholeness of the music and sparkles shinning 143 iam grateful.
The OG rhythm game is finally back. From what I’ve seen in older reviews, many players were disappointed because the game launched without the classic 2D mode, which made the experience feel quite different from the original O2Jam. That criticism was understandable. However, it’s great to see the developers actively improving the game and listening to the community. The recent updates are definitely a positive sign. I really hope the team continues adding more features in the future, especially online multiplayer, along with more content and improvements. Most importantly, I’d love to see even more support and development for 7K mode, because in my opinion, that’s where O2Jam is at its best. Keep up the good work, and I’m looking forward to seeing this game grow!
