For those who'd like to play o2jam in 2021, you can download it on o2jam.com.ph. Update 2023: Unfortunately, O2jam interval is now permanently closed. You can download another o2jam private server called C2Jam in this link web.c2jamgame.com/download
I was searching O2Jam and just want to know if the game is still alive. *It's indeed.* And how do you play the online version? Usually I play O2Mania (offline version)
