We've posted a small update:
* Added Simplified Chinese
* Added Japanese (including audio!)
* Upgraded to Unity 5.5.2p4
Coming soon will be German and Traditional Chinese.
Regarding multiplayer, we know many of you are anxiously awaiting it. The beta is extremely closed to being finished, and we hope to release it sometime in April.
Apologies for the long wait, it's close now, please stay tuned!
