So I have some initial news. I have done a real quick test on my 3 systems and the demo launches on 2 of the 3. It does crash on one system when launching through the Itch.io app. I have already sent a bug report to Itch.io in case it is with their app. The error I got was "Exit code 0xffffffff (-1) for (nw)". I tried copying the entire error code from the log but it won't allow me to copy the text as it is in the app. My other 2 systems it launches fine on though through the app.
My systems where it worked:
AMD FX-6100 | 16GB DDR3-1333 CL | EVGA GT 730 1GB | Mesa 19.2.8 | Trisquel 9.0 | Mate 1.20.0 | Kernel 4.15.0-106-generic

The system that crashed on:
