Often I open a file archive and if I find only an .x86_64 as executable file I delete it very quickly. For 32 bit versions only .x86 .x86_32 or .i686 should be used. The game works for me with MX 15 Debian Jessie 32 bit. However, I have not really understood it yet. The control seems to be very difficult. Possibly the game runs too fast.
