Yes i'm currently playing the chinese set, most of the npc's are English and I've been told by a GM they aim to have multiple languages to allow worldwide gameplay. I put some screenshots on Facebook to show some of my old wemade friends.
All of the features from assassin spells, crit pigs, leader boards, lava temple, ice tiger and so on all working - not strong enough to go anywhere like there yet only level 48 but they increase peoples levels every 48hours or so by like 2 so will eventually get there.
There is a few bugs as mentioned - I was told that they didn't manage to get any of the NPC's so they are working on re-adding them. The majority of added npc's that i've seen are only in chinese so they may or may not translate them later. I've also been told that the cave system's with the TreasureBox and invasions aren't working alongside the events like NumaHill due to there being no scripts.
P.S. i've just been speaking to the GM and asked if they would need my help translating due to some confused sentences and wording. The gm said they would consider inviting me to help them - may get more information soon.
