Hi there, just adding my positive feedback here, too, using (K)Ubuntu 14.04LTS and 16.04LTS
Exact Version: Ubuntu 16.04.3 LTS - Kernel 4.4.0-94-generic #117-Ubuntu SMP Tue Aug 29 08:13:56 UTC 2017 x86_64
NVidia/Intel graphics GK107M [GeForce GT 750M]
=> No problems whatsoever, 44 year old guy and 13 year old son having the fun of our lives :)
BTW: ZIP uses a Windows like attribute system, so the execute flag is not saved in ZIPs. If you tgz or bz2 the files, the linux flags will be preserved.
Thanks for a wonderful game and all the effort you put into the steady flow of updates and forum responses.
