The Appimage does not work on Any Linux based on Ubuntu 18.04 as I am using......this is because Appimages to be universal need to be compiled on Ubuntu 16.04 LTS or CentOS for the lower glibc versions they use. Can I recommend you guys do this henceforth and also maybe recompile Bugdom 2 to to ix this issue? otherwise that is eliminating alot of linux Distros and users. All the other games like Bugdom 1 and the rest work fine.
