As MN115 said we are on Unreal Engine and yes, that's possible.
We've already contacted some Friends And Collaborators with linux to debug the issue and resolve it. (in a short time i hope)
With a rapid test on ubuntu after the compiling it seemed to work , but it's our first linux build, maybe i missed something or there have been some problem during the upload i guess.
Thanks for the info, i'll try to solve the problem
