I tried running your game but it did not work. I'm using Ubuntu 18.04 with a cybertron i5 1050 ti machine

Quite strange, I run on parrot OS(debian dist) without problems.
from LDD I see that not many libs are needed. You should check. Maybe something is broken.
What kind of error you get?
I use laptop i7-4600MQ, quite oldy CPU and no graphic card at all.
