I am from near Heidelberg, just buyed the game and played the browser version. There are some memories of 7 Cities of Gold and Heart of Africa comig back.
I am just wondering how to start the game under Linux (Ubuntu 16.04). I've dowloaded the game from Humble Bundle. The version file says "0.36.5"
Starting "electron" from the folder gets the message:
"./electron: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory".
