Yes, I am a German player, but I am not sure If can spare 2 hours in the evening on normal days.
Just watch out for me in the lobby 

I had some severe trouble to get Mule playing on OSX 10.9 (Maveriks) unsing JDK 1.7  
java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

Trying it with the default java crashed (when starting a game) with
Dec 08, 2013 11:13:34 AM com.turborilla.mule.view.MuleGameContainer$1 run
INFO: Pixel format: Samples=0 Alpha=0 Depth=8 Stencil=0
_NSJVMLoadLibrary: NSAddLibrary failed for /libjawt.dylib
JavaVM FATAL: lookup of function JAWT_GetAWT failed. Exit

log_init.txt contains

I finally made it work by installing JDK 1.6 (as the game advised me first) and then calling

Code:

cd /Applications/mule.app/Contents/Resources/Java/data/
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Commands/java -Xms256m -Xmx1024m -Djava.library.path=lib -jar data.jar

This must me done in the Terminal.app
