Hello!
I tried your linux build because I saw it was untested,
the linux version does load and opens but i cant manage to enter any level. looking into the console i can see an error saying "map move_tut1 does not exist" .
I guess this is as far as I go with the native build, game looks good from the pictures keep working on it ! :D
ps you can open the console with F1 maybe a good idea to disable that next build <.<
