The latest Unity games that work on my system are built with Unity 4.6.4 or 5.0 beta. I am using MX-15 Debian Jessie 32 bit.
Hey, I have been doing some research and it seems that some unity libraries do not support 32bit Linux systems since like 2019. Therefor Unity Games don't support those systems anymore since then.
Nothing I can do here, sorry.
